Background: CD81, also called TAPA-1, is a type III transmembrane protein that is broadly expressed on cells of hematopoietic, neuroectodermal and mesenchymal origin. CD81 is believed to be involved in both cell growth and signal transduction. It can be present as a multimolecular complex in association with CD37 and/or CD53, or on the surface of B cells in association with CD19, CD21 and/or MHC class II antigens.

Purification and Purity: ProA affinity purified

Storage and Stability: Store at +4°C after thawing. Aliquot store at -20°C or -80°C. Avoid repeated freeze / thaw cycles.

Specificity: TAPA1/CD81 polyclonal antibody detects endogenous levels of TAPA1/CD81 protein.

Bioworld Molecular Weight: 20 kDa

Note: For research use only, not for use in diagnostic procedure.

Extra Notes: Western blot analysis of CD81 on different lysates using anti-CD81 antibody at 1/1,000 dilution.
