Chimeric antigen receptor T (CAR-T) cells are promising treatments for hematologic and solid malignancies. CAR-T cells can recognize and eliminate neoplastic cells expressing specific protein antigens. However, the current generation of CAR-T cells cannot distinguish between neoplastic and normal cells that may also be expressing the same antigen, thus potentially resulting in “on-target/off-tumor” toxicity. In this GEN webinar, we will review the RNAscope™ in situ hybridization (ISH) method and show applications of the technology in the CAR-T cell and immuno-oncology fields. We will demonstrate how RNAscope ISH can be utilized to identify novel CAR-T cell targets and subsequently qualify monoclonal antibodies directed against those targets for immunohistochemistry. We will show how ISH can be used to predict CAR-T cell target organ toxicity in preclinical models. Finally, we will discuss optimal preparation of tissues, cell pellets, and cytospin slides for evaluation by ISH. You Will Learn

- How RNAscope ISH technology can streamline your target identification and selection workflows

- The advantages of using ISH for immunotherapeutic target cell selection

- How ISH evaluation of target expression in normal tissues can be used to predict CAR-T cell induced toxicity

- Optimal tissue, cell pellet, and cytospin slide preparation for RNAscope ISH
