Analysis of IgA (Human, Non-human primate) by MSD Hypersensitive Multi-Factor Electrochemiluminescence Analyzer (CAT#: STEM-MB-0274-LGZ)

Introduction

Immunoglobulin A (IgA) is divided into serotype and secretory type. It is the antibody second only to IgG in serum, accounting for 15%-25% of the total immunoglobulin. It has a high content in extraneous secretions, such as colostrum, saliva, tears, intestinal secretions and bronchial secretions, and plays an important role in preventing infection. Secretory IgA is a dimer with stable properties and high local concentrations. It is the main immunoglobulin in mucous secretions, including tears, saliva, sweat, colostrum and secretions of urogenital tract, gastrointestinal tract, prostate and respiratory epithelium.
