The Human T-bet (TBX21) ELISA Kit is specifically designed for the precise measurement of T-bet levels in human samples such as serum, plasma, and cell culture supernatants. This kit offers exceptional sensitivity and specificity, guaranteeing accurate and consistent results for a variety of research purposes. T-bet, also known as TBX21, is a transcription factor that plays a critical role in regulating the immune response and the differentiation of T cells. It is crucial for the development and function of specific immune cells, including T-helper type 1 cells, which are involved in the defense against intracellular pathogens.
The detection of T-bet levels is essential for understanding the immune response in various diseases, including autoimmune disorders, infectious diseases, and cancer. This ELISA kit provides researchers with a valuable tool for studying T-bet expression levels and exploring its role in immune-mediated conditions, ultimately paving the way for the development of targeted treatments and therapies.

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.
