Recombinant Human CD8A protein, His-tagged

Specification :
| 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 acts as a coreceptor with the T-cell receptor on the T lymphocyte to recognize antigens displayed by an antigen presenting cell in the context of class I MHC molecules. The coreceptor functions as either a homodimer composed of two alpha chains or as 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 alpha chain. Multiple transcript variants encoding different isoforms have been found for this gene. | Source : E. coli | Species : Human | Tag : His | Form : 25mM Tris, pH8.0, 150 mM NaCl, 10% glycerol, 1 % Sarkosyl. | Molecular Mass : 19.4 kDa | Purity : > 80% as determined by SDS-PAGE and Coomassie blue staining | Storage : Store at -80 centigrade.
