T Cell Isolation

Begin your immunotherapy process on a strong footing. Accurate, efficient, and reproducible isolation of T cell populations will lay the groundwork for a successful cell therapy program. Rigorous analysis of your cell populations for phenotype and viability as well as the lack of contaminating cell types is critical to confirm that your isolation procedure is effective.

T Cell Exhaustion

For effective T cell therapies, it is important to avoid overactivation of the cells which can lead to T cell exhaustion. This balance may be dependent on the affinity and number of interactions between the T cell therapy and its target cells. Verify the functional potential of your T cells by analyzing the expression of exhaustion markers such as PD-1 and CTLA-4.

The CAR ToolKit: Progress and Challenges in CAR-T/NK Cell R&D and Mfg

With numerous clinical trials underway and multiple CAR-T cell products now approved, solving the current obstacles when manufacturing CAR-T/NK cell products continues to be a pressing issue for the cellular immunotherapy field. Watch this webinar, hosted by BioInsights, to learn about the current challenges, latest progress, and innovation facing CAR-T and CAR-NK cell development.

T Cell Characterization

Final T cell product characterization should encompass all your defined critical quality attributes (CQAs) to ensure that your product is as safe as possible for in vivo administration. Orthogonal CQA testing methods analyze unrelated parameters of the product and include phenotypic characterization of the cells, secretory profile, and purity (e.g. lack of undesired cell types and particulates).

T Cell Phenotype

Characterize the cell surface receptors on your T cells thoroughly to determine if they exhibit the correct phenotype for the cell type and activation status you need. In addition, measure population heterogeneity to determine if the count of contaminating cells is low enough to meet your specifications.
