表達(dá)區(qū)間及表達(dá)系統(tǒng)（Source）
Cynomolgus CD8 alpha Protein, His Tag (CDA-C52H4) is expressed from human 293 cells (HEK293). It contains AA Asn 63 - Asp 223 (Accession # XP_005575419.2).
Predicted N-terminus: Asn 63
蛋白結(jié)構(gòu)（Molecular Characterization）
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 19.6 kDa. The protein migrates as 20-30 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
內(nèi)毒素（Endotoxin）
Less than 1.0 EU per μg by the LAL method / rFC method.
純度（Purity）
>95% as determined by SDS-PAGE.
>95% as determined by SEC-MALS.
制劑（Formulation）
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

背景介紹
Integral membrane glycoprotein that plays an essential role in the immune response and serves multiple functions in responses against both external and internal offenses. Interacts simultaneously with the T-cell receptor (TCR) and the MHC class I proteins presented by antigen presenting cells (APCs). In turn, recruits the Src kinase LCK to the vicinity of the TCR-CD3 complex. In NK-cells, the presence of CD8A homodimers at the cell surface provides a survival mechanism allowing conjugation and lysis of multiple target cells. CD8A homodimer molecules also promote the survival and differentiation of activated lymphocytes into memory CD8 T-cells.
