The Rat Secretory Immunoglobulin A (sIgA) ELISA Kit is a powerful tool for the accurate measurement of secretory immunoglobulin A levels in rat samples. This kit is designed for use with rat serum, plasma, and other biological fluids, providing researchers with a reliable and sensitive method for detecting sIgA levels. Secretory immunoglobulin A is an important component of the immune system, playing a crucial role in mucosal immunity and providing protection against pathogens at mucosal surfaces. Abnormalities in sIgA levels have been linked to various immune disorders and inflammatory conditions, making it a valuable biomarker for research and clinical studies.
With its high sensitivity and specificity, the Rat sIgA ELISA Kit offers researchers a robust and accurate solution for measuring sIgA levels in rat samples. This kit is suitable for a wide range of applications, including basic research, drug development, and diagnostic testing. Invest in the Rat sIgA ELISA Kit today to advance your research in immunology and related fields.

Step
Procedure
1
Reagent & Plate Preparation: Equilibrate reagents and TMB substrate to room temperature. Set standard, test sample and control (zero) wells on the pre-coated plate and record their positions.
2
Primary Incubation: Prepare standards, samples, blanks and load into designated wells. Incubate plate at 37°C for 90 minutes to allow antigen binding.
3
Detection Antibody Binding: Add biotin-labeled detection antibody and incubate at 37°C for 60 minutes.
4
HRP-Streptavidin Binding: Add HRP-Streptavidin (SABC) and incubate at 37°C for 30 minutes.
5
Color Development: Add TMB substrate and incubate in the dark for 10–20 minutes.
6
Stop Reaction & Reading: Add stop solution and measure absorbance at 450 nm immediately.
Sample Type
Protocol
Serum
Allow blood to clot, centrifuge at 1000 × g for 20 minutes, collect supernatant supernatant and store appropriately.
Plasma
Collect using anticoagulant tubes, centrifuge at 1000 × g for 15 minutes at 2–8°C and collect plasma.
Tissue Homogenate
