Analysis of Vitamin D Binding Protein (Human) by ELISA (CAT#: STEM-MB-1267-LGZ)

Introduction

Vitamin D binding protein (DBP) is mainly synthesized by the liver and widely distributed in many tissues and organs throughout the body. Recent studies have found that DBP not only binds, dissolves and transports vitamin D and its metabolites in the blood circulation, but also has immune regulatory functions independent of vitamin D transport, and has a certain relationship with the occurrence and development of inflammation and tumor.




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.
