Principle of the Assay: CD8 ELISA kit applies the competitive enzyme immunoassay technique utilizing a polyclonal anti-CD8 antibody and an CD8-HRP conjugate. The assay sample and buffer are incubated together with CD8-HRP conjugate in pre-coated plate for one hour. After the incubation period, the wells are decanted and washed five times. The wells are then incubated with a substrate for HRP enzyme. The product of the enzyme-substrate reaction forms a blue colored complex. Finally, a stop solution is added to stop the reaction, which will then turn the solution yellow. The intensity of color is measured spectrophotometrically at 450nm in a microplate reader. The intensity of the color is inversely proportional to the CD8 concentration since CD8 from samples and CD8-HRP conjugate compete for the anti-CD8 antibody binding site. Since the number of sites is limited, as more sites are occupied by CD8 from the sample, fewer sites are left to bind CD8-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The CD8 concentration in each sample is interpolated from this standard curve.
NCBI and Uniprot Product Information
NCBI Description
The CD8 antigen is a cell surface glycoprotein found on most cytotoxic T lymphocytes that mediates efficient cell-cell interactions within the immune system. The CD8 antigen, acting as a coreceptor, and the T-cell receptor on the T lymphocyte recognize antigens displayed by an antigen presenting cell (APC) in the context of class I MHC molecules. The functional coreceptor is either a homodimer composed of two alpha chains, or a heterodimer composed of one alpha and one beta chain. Both alpha and beta chains share significant homology to immunoglobulin variable light chains. This gene encodes the CD8 beta chain isoforms. Multiple alternatively spliced transcript variants encoding distinct membrane associated or secreted isoforms have been described. A pseudogene, also located on chromosome 2, has been identified.

Uniprot Description
CD8B: Identifies cytotoxic/suppressor T-cells that interact with MHC class I bearing targets. CD8 is thought to play a role in the process of T-cell mediated killing. 8 isoforms of the human protein are produced by alternative splicing.

Product Notes
The Goat CD8 cd8b (Catalog #AAA738019) is an ELISA Kit and is intended for research purposes only. The product is available for immediate purchase. The AAA738019 ELISA Kit recognizes Goat CD8. It is sometimes possible for the material contained within the vial of "Cluster of Differentiation 8, ELISA Kit" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
