GTOnco™ T Cell Persistence & Trafficking Assay

T persistence and trafficking properties are important factors affecting the anti-tumor activity of I-O products. Generally, after adoptive T cell transfer, the T cell persistence is likely to promote long-term anti-tumor effects. In addition, following antigen-specific stimulation, the trafficking properties of T cells are changed and these activated and effector T cells acquire the ability to effectively and specifically home to other organs. Based on the outstanding expertise and rich experience, Creative Biolabs has developed the fast, reliable and affordable T cell persistence & trafficking assay platform to support your gene therapy-based I-O drugs development. We also provide one-stop preclinical in vivo service for our clients to evaluate the anti-tumor effects of I-O products, especially in the field of CAR-T or TCR-T therapy.

In adoptive T cell transfer therapy, the limited replicative lifespan of TCRs inhibits the long-term persistence and expansion of these cells in vivo, which further affects their long-term therapeutic effects. T trafficking property including the stimulation of the recruitment of immune cells and their infiltration into the tumor masses is primordial for effective anti-tumor immune responses to counter disease progression. At GTOnco™, we provide an advanced and effective in vivo assay platform to help our clients improve the T persistence and their therapeutic potential. Meanwhile, we also offer the best-fit in vivo T cell trafficking assays to visualize organ-specific homing of T cells. We are pleased to share our experience for you to evaluate gene therapy-based I-O drug candidates with possible properties that can affect the migration and persistence of immune cells, and in turn influences their anti-tumor ability.
