Human SERPINB9 ELISA Kit (HUFI08485)

The Assay Genie human SERPINB9 quantitative immunoassay kit enables researchers to measure SERPINB9 protein levels in biological specimens using a standard ELISA workflow. SERPINB9 (also called PI-9 or cytoplasmic antiproteinase) is a granzyme B inhibitor expressed by cytotoxic T lymphocytes, NK cells, and certain tumor cell populations, where it shields effectors from self-inflicted proteolysis during immune killing. Quantifying SERPINB9 expression is therefore relevant to studies of immune privilege, transplant tolerance, tumor immune evasion, viral immune escape, and inflammatory disease models.

Each kit ships with pre-coated microplate strips, ready-to-use reagents, and a detailed protocol supporting reproducible standard curves. Researchers typically run the assay alongside prepared standards to interpolate unknown sample concentrations, with absorbance read on a standard plate reader. The kit is intended for research use only and is not validated for diagnostic procedures. Store unopened components refrigerated and protect them from light exposure to maintain reagent stability across the shelf life of the product. Assay Genie provides technical support for assay optimization and troubleshooting.
