Cell-based immunotherapies consist of cells that are manipulated, and often gene-modified, providing the capacity to treat diseases like tumors. These therapies are composed of a heterogeneous population of cells, both phenotypically and functionally, in which not all the cells have the same effectiveness in targeting and treating the disease.
The characterisation of cell-based immunotherapies today pri-marily relies on bulk analytical tests, which typically overlook the inherent heterogeneity of these products. As a result, the ability to predict the in-vitro potency of these therapies remains a significant unmet need.
Single-cell technologies offer the potential to perform a deeper characterisation of immunotherapies, providing critical insights for the cell therapy industry as it seeks to understand the roles of the diverse cell populations that comprise therapeutic batches.
Thanks to the collaboration with Cellply, Eurofins BioPharma Product Testing Italy can now offer the VivaCyte technology, a single-cell analytical tool that delivers reproducible phenotypical and functional characterization at a single cell level using minimal amounts of valuable product samples. This cutting-edge solution allows a deeper understanding of the complexity that underlies heterogenous immune cell therapy candidates, offering an insight of their potency and persistence. The high throughput of single-cell data that VivaCyte can analyze also enables the generation of a novel Unified Killing Score (UKS). This innovative approach combines the single-cell granularity of this analysis with an easily interpretable score that facilitates direct comparisons between immune cell samples (e.g. from different donors or different gene edits), or across different cell therapy batches.
Identifying the ideal starting material cells and/or the most effective manufacturing processes, which feature higher serial killing activity and better kinetics, can enable the development of more potent products capable of generating a therapeutic response in the patient.
Eurofins BioPharma Product Testing Italy can offer clients comprehensive single-cell functional characterization services for cell-based immunotherapies to improve and save lives. For more information visit: www.eurofins.it/biopharma/comprehen-sive-cell-and-gene-therapy-testing-capabilities/
Eurofins PHAST GmbH helps clients detect and control impurities in pharmaceutical drugs earlier
Peter Kleine, Reference Standards Business / Marketing Specialist, Eurofins PHAST GmbH, dietrich-peter.kleine@bpt.eurofinseu.com
Impurities – a risk for drug manufacturers and patients
Impurities detected too late in the development phase of a pharmaceutical product can delay product approval. Impurities that are only discovered during the production process can result in delays in market supply. If contaminated pharmaceutical drugs are already on the shelf, expensive recalls and official measures are inevitable. The consequences for the manufacturer are a loss of patient confidence in the efficacy of the preparations on offer, including a loss of brand image and a loss of confidence in the effectiveness of regulatory controls.
Pharmaceutical Analytical Impurities for Early Detection
Impurities can occur during the entire product life cycle of a pharmaceutical drug – during development, raw material purchasing, production, transportation, and storage. In order to detect an impurity and assess its degree at an early stage in these complex processes, a supplementary tool is required in addition to the use of official reference standards. Many years of experience in cooperation with science, industry, and authorities have led USP to develop its own product range, the Pharmaceutical Analytical Impurities – PAI. PAIs are analytical reference materials for the early detection of impurities in analytical research and development and process development.
The USP PAI portfolio already includes over 550 analytical reference materials for over 130 active pharmaceutical ingredients (APIs) in 20 therapeutic categories. Each USP PAI is supported by its own product information sheet with details of identity and purity.
PAIs can be used in various applications:
- Performing analytical testing during early feasibility studies for formulations
- Determination of degradation impurities, e.g. during stress studies
- Conducting spiking studies during process R&D
- Identification of unknown impurities formed under ICH stability conditions
- Testing for and profiling impurities that are not listed in the monographs for pharmaceutical drugs and drug products
PAIs can help reduce the risk of unsafe levels of impurities in the manufacturing process and increase pharmaceutical drug safety for patients. The availability of nitrosamine impurities (NSDRIs) is just one example.
Order PAI and Reference Standards easily online
Eurofins PHAST GmbH has created a webshop to provide clients with the best possible support when purchasing official reference standards and PAIs. Here clients can conveniently select and order the reference standards and PAIs needed for analyses. Register and test at: www.reference-standards.com/ or contact us at reference-standards@bpt.eurofinseu.com.
Reference standards and PAIs can only be obtained by specialists (pharmaceutical industry – e.g. manufacturers of original preparations and generics as well as phytopharmaceuticals, institutional laboratories, pharmacies).
With USP’s guidelines emphasising quality standards of mRNA analytical methods for characterisation and release testing, Eurofins BPT delivers solutions
Jeremy Johnston, Scientific Ad-visor, Drug Product Operations, Eurofins BioPharma Product Testing, jeremy.johnston@bpt.eurofinsus.com; Joe Page, President, Eurofins Advantar Laboratories, joe.page@bpt.eurofinsus.com

The global mRNA therapeutics market is expected to expand tremendously in the next 10 years due to these modalities being more effective, faster to design and produce, as well as more flexible compared to traditional approaches. In order to emphasize the quality and consistency of analytical methods used for mRNA-based vaccines and therapies, the United States Pharmacopeia (USP) has recently published guidelines on analytical methods covering the characterization and release testing for mRNA drug substances and mRNA drug products. In addition, the European Pharmacopoeia (Ph. Eur.) Commission re-leased three guidelines in 2023 with the goal of setting common quality standards across Europe related to the production and control of mRNA-LNP medicinal products and their components. While there are several common methods required to ensure safe-ty, quality, and purity let’s focus on a few of the more challenging assays that pharmaceutical organisations often lack expertise and instrumentation availability. The 5’ cap structure and 3’ poly-adenosine tail are crucial modifications that are introduced either co-transcriptionally or in a post-tran-scriptional reaction on the mRNA construct. The percentage of capped and polyadenylated mRNA, as well as the poly(A) tail length and distribution, will have a direct impact on the translational efficiency. Assessing these structural features requires complex methodology and instrumentation and would typically involve digesting the mRNA with enzymes that allow isolation of the relevant 3’ or 5’ end and analysis, using oligo specific synthesized probes. Both the efficiency of 5’ capping and poly A tail length can be characterized by LC/MS/MS with a high-resolution mass spectrometer (Q-TOF or Orbitrap) with IP-RP-HPLC.
An appropriate potency assay is a key CQA for any mRNA product. Eurofins BioPharma Product Testing has experts in the develop-ment and validation of potency assays for both mRNA therapeutics and vaccines. These methods are usually based on the transfection of appropriate cell lines with the mRNA drug substance or product, followed by monitoring of an induced effect, such as protein ex-pression or other quantitative effect in the cell. While the endpoint readout may be an ELISA, often Flow Cytometry can be utilized for specific mRNA products with complex mechanisms of action.
LNPs (Lipid nanoparticles) are currently the foremost non-viral delivery vector employed to transport mRNA into cells. LNPs are typically composed of four components: an ionizable cationic lip-id, a helper phospholipid, cholesterol, and a PEGylated lipid. These lipids encapsulate the mRNA payload and protect the nucleic acid core from degradation. Characterization and monitoring of the LNP physicochemical properties such as particle size, lipid content and composition, and percent mRNA encapsulation are required to support regulatory submissions. These CQAs can be monitored by DLS, zeta potential, HPLC-CAD, and RiboGreen assays.
Eurofins BioPharma Product Testing offers full mass spectrometry, cell-based potency, and flow cytometry GMP capabilities from U.S. coast to coast in Lancaster, PA; Columbia, MO; as well as San Diego, CA, locations.

Do your products meet critical attributes for the entire shelf life?
Barbara Paiola, Business Unit Manager, Eurofins BioPharma Product Testing Italy, Barbara.Paiola@bpt.eurofinseu.com

Antimicrobial Effectiveness Tests (AET) or challenge tests on drug products are typically performed during development studies sup-porting the Marketing Authorisation Holder to define the formula-tion, address microbial hurdles, and guarantee that the products meet their critical attributes for the entire shelf life.
Normally the shelf life for closed products is established during stability studies. Additionally, evaluations on multi-dose products, such as aqueous or reconstituted preparation, topical creams or ointments, solid dose tablets, or capsules packed in containers that could expose them to light, temperature, and humidity after opening, should be performed as well. Consequently, in-use stability studies can be designed to assess intrinsic microbiological robustness of multi-dose drug products.
Even if there are no recent specific guidelines, in-use stability is more and more frequently being requested by regulatory agencies for all types of multi-dose products both preserved and self-pre-served. It’s typically indicated to perform chemical tests, such as assay or preservative content, packaging tests, or tests similar to container integrity tests to assure the sterility of, for example, eye drops packaging when in use, and microbiological tests such as AET.
Usually, references for challenge tests are USP or Ph.Eur., but for in-use stability purposes, time points should be selected taking into consideration the real use of the products according to label instructions and the additional strain of a typical home environment, introducing for instance, Staphylococcus epidermidis in the protocol. An example of a sampling plan for a product diluted in an infusion bag may include testing at T0, T2, T4, T8, T24, and T48 (time expressed in hours) with storage at 5°C and 30°C. The test is then completed with the verification that microorganisms are able to grow if present or added to the product. Eurofins BioPharma Product Testing partners with clients to work on defining protocols and running them in our laboratories and solving testing challenges that may arise when approaching these requirements.
