Human Granzyme B PharmaGenie ELISA Kit (SBRS0656)

Granzyme B is a serine protease released by cytotoxic T lymphocytes and natural killer cells that triggers caspase-mediated apoptosis in target cells, making it a valuable biomarker in immunology, oncology, and transplant research. The Assay Genie PharmaGenie ELISA kit provides quantitative measurement of human Granzyme B across multiple sample types, including cell culture supernatant, plasma, and serum. Built on a 96-assay plate format, the kit is configured for research use only and supports batch processing of study samples in immune-monitoring workflows. Granzyme B concentrations serve as a readout of cytotoxic lymphocyte activity in vitro and have been applied in studies of tumor-infiltrating lymphocytes, viral infection models, autoimmune disease mechanisms, and immunotherapy response. Each kit ships with pre-coated wells and all reagents required to run the standard protocol, and the procedure can be performed using conventional microplate reader instrumentation. Components should be refrigerated upon arrival to preserve the stated shelf life indicated on the kit label. The workflow fits standard laboratory practices for protein quantification, allowing integration into broader cytokine profiling panels and cellular immunology studies.
