Human Signal Regulatory Protein Alpha (SIRPa) ELISA Kit

SIRPa (Signal Regulatory Protein Alpha) is a key inhibitory immune receptor that regulates phagocytosis through its interaction with CD47, and altered expression is implicated in tumor immune evasion, autoimmune disease, and neuroinflammation. The Assay Genie SIRPa ELISA Kit provides a quantitative immunoassay for measuring endogenous human SIRPa protein in experimental samples, supporting research into macrophage signaling, transplant tolerance, and cancer immunotherapy targets.

Built for flexibility in sample handling, the assay accepts tissue homogenates and cell lysates, accommodating workflows that range from cultured cell line profiling to ex vivo tissue analysis. Reagents are supplied in a 96-assay configuration with absorbance readout on a standard plate reader, and the kit is intended for research use only. Each pack contains all necessary reagents for 96 determinations, fitting into immunology, oncology, and neuroscience pipelines where SIRPa pathway activity is being characterized across patient-derived samples or animal model tissues.
