Analysis of IL1RL1/ST2 (Human) by ELISA (CAT#: STEM-MB-0960-LGZ)

Introduction

As a new biomarker, ST2 has been widely used in recent years and is one of the main directions of future development. ST2, a protein biomarker of cardiac stress encoded by the IL1RL1 gene, is a member of the interleukin-1 receptor family, expressed as transmembrane (ST2L) and soluble isotype (sST2) subtypes. sST2 has been shown to be physiologically associated with cardiac hypertrophy, fibrosis, and ventricular dysfunction.




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.
