CD47 [Biotinylated] : SIRP alpha Inhibitor Screening ELISA Kit
背景（Background）
CD47 is a transmembrane protein, a cell surface glycoprotein molecule belonging to the immunoglobulin superfamily that binds to a variety of proteins, including integrins, thrombospondin 1, and signal regulatory protein-α (SIRPα). In recent years, accumulating data have demonstrated that the CD47-SIRP-α axis is a key immune checkpoint in different cancers, including hematological malignancies, similar to PD-1/PD-L1 in solid tumors. Cd47-sirpα blockade has become a next-generation immune checkpoint blocking strategy for various malignancies after PD-1/PD-L1.
原理（Assay Principles）
This inhibitor screening ELISA kit is designed to facilitate the identification and characterization of new CD47 pathway inhibitors. The assay takes advantage of our in house-developed binding of biotinylated human CD47 to immobilized human SIRP alpha in a functional ELISA assay, and employs a simple colorimetric ELISA platform. Briefly, we provide you with a human Biotinylated CD47 protein, a human SIRP alpha protein, an anti-CD47 neutralizing antibody (as method verified Std.), and Streptavidin-HRP reagent.
Your experiment will include 4 simple steps:
a) Coat the plate with human SIRP alpha.
b) Add your molecule of interest to the tests.
c) Add human CD47-Biotin to bind the coated SIRP alpha.
d) Add Streptavidin-HRP followed by TMB or other colorimetric HRP substrate.
e) Finally, the half maximal inhibitory concentration (IC50) of your compound to CD47: SIRP alpha binding will be determined by comparing OD readings among different experimental groups.
應(yīng)用說明（Application）
