Product type
Primary Antibodies
TargetCD8B
ApplicationsWB, ELISA
Species / reactivityHuman, Rat, Mouse
Expression systemIsoform 1, isoform 3, isoform 5, isoform 6, isoform 7 and isoform 8 are expressed in both thymus and peripheral CD8+ T-cells. Expression of isoform 1 is higher in thymus CD8+ T-cells than in peripheral CD8+ T-cells. Expression of isoform 6 is higher in peripheral CD8+ T-cells than in thymus CD8+ T-cells.
PurityThe antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen.

Product description

CD8B rabbit pAb is a research-use antibody from ELK Biotechnology for studying CD8B in WB, ELISA workflows with listed reactivity for Human, Rat, Mouse. Specifications and supporting documents below should be reviewed when planning the experiment.

Background

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.
