Analysis of B7-H6 (Human) by ELISA (CAT#: STEM-MB-0685-LGZ)

Introduction

B7-H6 is a ligand for the NK cell-activating receptor NKp30, which triggers cytotoxicity and cytokine secretion against tumor natural killer (NK) cells. Both forms of B7-H6 (cell surface B7-H6 and soluble B7-H6 (sB7-H6)) are detected in primary tumors and the tumor microenvironment, but are rarely found in normal tissues.




Principle

Enzyme-linked immunosorbent assay (ELISA) is an enzyme-labeled solid phase immunoassay technique. Its basic principle is to bind the antigen (or antibody) to the solid phase carrier, and the antigen (or antibody) and a certain enzyme link to enzyme labeled antigen (or antibody). During detection, the sample to be tested and the enzymic antigen (or antibody) react with the antigen (or antibody) on the solid phase carrier according to certain procedures, and then remove the unreacted part by washing method. After adding the substrate, the substrate is catalyzed by the enzyme on the solid phase carrier to produce colored substances. Through qualitative or quantitative detection of the amount of colored products, the content of the substance to be measured in the sample can be determined.

Applications
