All CD81 reagents are produced in house and quality controlled, including 7 CD81 Antibody, 52 CD81 Gene, 8 CD81 Lysate, 8 CD81 Protein, 3 CD81 qPCR. All CD81 reagents are ready to use.
Recombinant CD81 proteins are expressed by HEK293 Cells with fusion tags as N-His, N-mouse IgG1-Fc, N-cleavage.
CD81antibodies are validated with different applications, which are FCM, ELISA.
CD81cDNA clones are full length sequence confirmed and expression validated. There are 13 kinds of tags for each CD81 of different species, especially GFP tag, OFP tag, FLAG tag and so on. There are three kinds of vectors for choice, cloning vector, expression vector and lentivrial expression vector.
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.
