別名	Lyt-2, Ly-35, Ly-B, CD8a molecule, Ly-2, BB154331, CD8 α
Construction	A DNA sequence encoding the CD8a (NP_001074579.1) (Met1-Tyr196) was expressed with a C-terminal polyhistidine tag. The purified protein was biotinylated in vitro.
Protein Purity	> 95 % as determined by SDS-PAGE.
分子量	20.3 kDa (predicted)

Endotoxin	< 1.0 EU per μg protein as determined by the LAL method.
Formulation	Lyophilized from sterile Sterile PBS. Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0. 01% Tween 80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA.
Reconstitution	A hardcopy of datasheet with reconstitution instructions is sent along with the products. Please refer to it for detailed information.
Stability & Storage	Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃. Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
Shipping	In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
Research Background	T-cell surface glycoprotein CD8 alpha chain, also known as CD8a, is a single-pass type I membrane protein. The CD8 glycoprotein is expressed by thymocytes, mature T cells and natural killer (NK) cells and has been implicated in the recognition of monomorphic determinants on major histocompatibility complex (MHC) Class I antigens, and in signal transduction during the course of T-cell activation. Both human and rodent CD8 antigens are comprised of two distinct polypeptide chains, alpha and beta. The Ig domains of CD8 alpha are involved in controlling the ability of CD8 to be expressed. Mutation of B- and F-strand cysteine residues in CD8 alpha reduced the ability of the protein to fold properly and, therefore, to be expressed. Defects in CD8A are a cause of familial CD8 deficiency. Familial CD8 deficiency is a novel autosomal recessive immunologic defect characterized by absence of CD8+ cells, leading to recurrent bacterial infections.
