The Bovine CD8a Cell Surface Glycoprotein (CD8 Alpha Chain) ELISA Kit (BOFI00139) is specifically designed for the accurate detection of CD8a levels in bovine samples such as serum and plasma. This ELISA kit offers high sensitivity and specificity, providing reliable and reproducible results for a variety of research applications. CD8a is an important cell surface glycoprotein that plays a crucial role in the immune system, particularly in cytotoxic T cell activation and function. It is a key marker for identifying T cell subsets and understanding their roles in immune responses to infections, autoimmune diseases, and cancer.
This ELISA kit is essential for researchers studying immunology, vaccine development, and immune-related diseases in bovine species. Overall, the Bovine CD8a Cell Surface Glycoprotein (CD8 Alpha Chain) ELISA Kit (BOFI00139) is a valuable tool for accurately measuring CD8a levels in bovine samples, providing valuable insights into immune responses and potential therapeutic targets.

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.
