CD81 / TAPA-1 Protein QC Testing

純度: (94.0%+4.4)% 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: Asp
分子量: 
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.
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.

CD81 / TAPA-1 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.

CD81 / TAPA-1蛋白背景綜述

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.
