The Human VIP (Vasoactive Intestinal Peptide) ELISA Kit is specially designed for the precise measurement of VIP levels in human serum, plasma, and cell culture supernatants. With its high sensitivity and specificity, this kit delivers accurate and consistent results, making it a valuable tool for various research purposes. VIP is a vital neuropeptide known for its role in regulating various physiological processes, including immune responses, neurotransmission, and smooth muscle relaxation.
Its dysregulation has been linked to conditions such as inflammatory bowel disease, asthma, and neurological disorders, highlighting its importance as a biomarker for studying and potentially treating these diseases. Overall, the Human VIP ELISA Kit offers researchers a reliable and efficient method for quantifying VIP levels, allowing for in-depth investigations into VIP's role in health and disease.

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
Homogenize tissue in PBS with protease inhibitors, centrifuge and collect supernatant.
Cell Culture Supernatant
Centrifuge at 2500 rpm for 5 minutes and collect clarified supernatant.
Cell Lysate
Lyse cells using lysis buffer with protease inhibitors, centrifuge and collect protein supernatant.
