Not applicable — "cynoTIGIT-CHO-K" refers to a research reagent, specifically a recombinant protein or antibody used in preclinical studies involving non-human primates (cynomolgus monkey). It is typically employed in immunological research and drug development to study immune checkpoint pathways, particularly the TIGIT (T-cell immunoreceptor with Ig and ITIM domains) pathway. Its main application lies in evaluating immune modulation in the context of cancer immunotherapy, autoimmune diseases, and infectious disease models. It may be used in vitro or in vivo to block or stimulate TIGIT signaling, helping researchers understand T-cell and NK-cell regulation. This reagent supports the development of human-targeted biologics by providing pharmacokinetic and pharmacodynamic data in relevant animal models.
