CD8 alpha & beta, CD8A & CD8B

Source

Mouse CD8A&CD8B Heterodimer Protein, His Tag&Tag Free (CDA-M52W3) is expressed from human 293 cells (HEK293). It contains AA Lys 28 - Tyr 196 & Leu 22 - Thr 175 (Accession # P01731-1 & P10300).

Predicted N-terminus: Lys 28 & Leu 22

Molecular Characterization
Other Tags and Version Biotin & Other Labeled Version

Mouse CD8A&CD8B Heterodimer Protein, His Tag&Tag Free, produced by co-expression of CD8 alpha and CD8 beta, has a calculated MW of 24.9 kDa (CD8 alpha) and 21.9 kDa (CD8 beta). Subunit CD8 alpha is fused with with a polyhistidine tag at the C-terminus and subunit CD8 beta contains no tag. The protein migrates as 30-33 kDa and 39-42 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

The protein is designed as a heterodimer.

Endotoxin

Less than 1.0 EU per μg by the LAL method / rFC method.

Purity

>95% as determined by SDS-PAGE.

>90% as determined by SEC-MALS.

Formulation

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

Background

The CD8αβ heterodimer is a key cell surface co-receptor on cytotoxic T lymphocytes. It binds to MHC class I molecules on antigen-presenting cells, stabilizing the interaction between the T-cell receptor (TCR) and the peptide-MHC complex. This binding is essential for T-cell activation, positive selection in the thymus, and the effector function of mature CD8+ T cells. The β-chain (CD8β) modulates the affinity of the interaction, contributes to signal transduction, and promotes the stable surface expression of the heterodimer.
