Recombinant Human CD81 Protein, N-mFc-tagged
Product Description
Cat
IMP-4309
Official Symbol
CD81
Product Overview
Recombinant human CD81 (NP_004347.1) (Phe113-Lys201) was expressed with the Fc region of mouse IgG1 at the N-terminus.
Description
CD81, also known as TAPA-1, belongs to the transmembrane 4 superfamily, also known as the tetraspanin family. Members of this family mediate signal transduction events that play a role in the regulation of cell development, activation, growth and motility.CD81 is a widely expressed cell-surface protein involved in an astonishing variety of biologic responses. It is related to adhesion, morphology, activation, proliferation, and differentiation of B, T, and other cells. On B cells CD81 is part of a complex with CD21, CD19, and Leu13. This complex reduces the threshold for B cell activation via the B cell receptor by bridging Ag specific recognition and CD21-mediated complement recognition.

Form
Lyophilized from sterile PBS, pH 7.4, 5 % trehalose, 5% mannitol and 0.01% Tween80.
Molecular Mass
The recombinant human CD81/mFc comprises 325 amino acids and has a predicted molecular mass of 36.4 kDa. The apparent molecular mass of the monomer is approximately 38-42 kDa in SDS-PAGE under reducing conditions due to glycosylation.

Phe113-Lys201
Endotoxin
< 1.0 EU/μg of the protein as determined by the LAL method
Purity
> 95 % as determined by SDS-PAGE
Storage
Samples are stable for up to twelve months from date of receipt at -20 to -80 centigrade.
Store it under sterile conditions at -20 to -80 centigrade. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
