Analysis of TECK/CCL25 (Human) by ELISA (CAT#: STEM-MB-1203-LGZ)

Introduction

Thymus-expressed chemokine (TECK; CCL25) is a small cytokine belonging to the CC chemokine family, also known as TECK (thymus-expressed chemokine). It is thought to play a role in the development of T cells. It is chemotactic for thymocytes, macrophages and dendritic cells. CCL25 acts by binding to the chemokine receptor CCR9. It is produced as a protein precursor containing 151 amino acids. The gene for CCL25 (scya25) is located on chromosome 19.




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
