種屬: Rat
表達宿主: Human Cells

CD8A / Lyt2 Protein QC Testing

純度: > 90 % as determined by SDS-PAGE SDS-PAGE
內**: < 1.0 EU per μg of the protein as determined by the LAL method
穩定性: Samples are stable for up to twelve months from date of receipt at -70℃
預測N端: Gln 27
分子量: 
The recombinant rat CD8A/Fc is a disulfide-linked homodimer. The reduced monomer comprises 404 amino acids and has a predicted molecular mass of 45 kDa. The apparent molecular mass of the protein is approximately 46 kDa in SDS-PAGE under reducing conditions due to glycosylation.
緩沖液: Lyophilized from sterile PBS, pH 7.4.
Normally 5 % - 8 % trehalose and mannitol are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
Please contact us for any concerns or special requirements.

CD8A / Lyt2 Protein Usage Guide

儲存方法: Store it under sterile conditions at -70℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
Reconstitution: A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.

CD8A / Lyt2蛋白背景綜述

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.
