Human CD8 alpha&beta Heterodimer Protein (CD8-HM1AB) Summary

Product Description

Recombinant Human CD8 alpha&beta Heterodimer Protein is expressed from HEK293 with His tag at the C-Terminus of CD8 alpha and Flag tag at the C-Terminus of CD8 beta.It contains Ser22-Asp182(CD8 alpha) acidic tail and Leu22-Pro170(CD8 beta) basic tail.

Product Background

CD8 alpha&beta (CD8αβ) is a heterodimeric form of CD8. CD8α is required for surface expression of CD8β. The extracellular IgV-like domain of CD8α interacts with the α3 portion of the class I MHC molecule. CD8αβ is expressed on human peripheral T cells and functions as a coreceptor and can greatly increase the sensitivity and breadth of antigen recognition by CD8+ peripheral T cells bearing TCR.

Shipping, Reconstitution, & Storage

Form
Lyophilized
Shipping
Shipped at ambient temperature.
Formulation
Lyophilized from 0.22um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution
Dissolve the lyophilized protein in distilled water. It is recommended to resuspend at 0.5 mg/mL if the lyophilized powder is 100 ug or less, at 1mg/ml for 500ug or 1mg lyophilized powder. Do not mix by vortex or vigorous shaking.
Stability And Storage
-20 to -80°C for 12 months as supplied from date of receipt.;-80°C for 3 months after reconstitution.;Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
