   Size B      500ug  $400
   Size C      1mg  $ 600
Clone  :  RKCD8
Isotype  :  IgG2a
Catalog no. :  RMA01732
  • Western blot: This monoclonal antibody has been tested in WB analysis of human CD8 . A suitable range of concentrations of this antibody for WB detection is 0.5-2 µg/ml.
This antibody was produced from a hybridoma resulting from the fusion of a mouse myeloma with B cells obtained from a mouse immunized with Human fetal thymocytes.
Species reactivity:

The IgG fraction of the tissue culture supernatant was purified by Protein A affinity chromatography.

Lyophilized from sterile filtered PBS solution at a concentration of 1mg/ml .
A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers
The lyophilized antibody is stable for at least 1 year  from date of receipt at -20° C.
Upon reconstitution, this antibody can be stored in working aliquots at 2° - 8° C , or at -20° C for six months without detectable loss of activity.

Avoid repeated freeze/thaw cycles.

The cell surface glycoprotein CD8 plays an important role in the development and function of MHC3 class I-restricted T cells. CD8 fulfils its function through interacting via its extracellular domain with MHC class I proteins and via its intracellular domain with the tyrosine kinase Lck (1, 2). An interaction of both the T cell receptor (TCR) and CD8 with MHC proteins enhances the adhesion between the T cell and the antigen- presenting cell.The coreceptor CD8 is expressed as a CD8ab heterodimer on major histocompatibility complex class I-restricted TCRab T cells, and as a CD8aa homodimer on subsets of memory T cells, intraepithelial lymphocytes, natural killer cells, and dendritic cells.
