- Extra Details:
- CD81, also known as TAPA-1 or Target of the antiproliferative antibody, is a 236 amino acid ~26 kDa multipass transmembrane protein belonging to the TM4SF family (UniProt: P35762). In rodents CD81 is expressed at much higher levels on resting B cells than on T cells, although increased expression on T cells is found following activation. C2433-12A induces homotypic aggregation of B cells and inhibits anti Ig and IL-4 induced proliferation (Maecker et al. 2000). C2433-12A requires the presence of both extracellular loops of TAPA-1 for binding. Mice lacking CD81 demonstrate reduced fertility through impaired oocyte-sperm fusion, double knockout CD81-/- CD9-/- mice are completely infertile suggesting complimentary roles in oocyte-sperm fusion (Rubenstein et al. 2006). Applications: Suitable for use in FLISA, Western Blot, Immunoprecipitation and Immunohistochemistry. Other applications not tested. Recommended Dilution: Immunohistochemistry (frozen): The recognized epitope is reported to be sensitive to formaldehyde fixation and tissue processing. Use of acetone fixation is recommened. Western Blot: non-reducing conditions Optimal dilutions to be determined by the researcher. Hybridoma: Spleen cells from immunized Armenian hamsters were fused with cells of the mouse PX3-Ag.8.653 myeloma cell line. Recommended Secondary Reagents: I1903-04T: IgG H&L (HRP) Pab Gt x Hm I1903-04Q: IgG H&L (FITC) Pab Gt x Hm Recommended Negative Controls: Hamster IgG Negative Control Storage and Stability: Store product at 4°C. DO NOT FREEZE! Stable at 4°C for 12 months after receipt as an undiluted liquid. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer. For maximum recovery of product, centrifuge the original vial prior to removing the cap. Note: Applications are based on unconjugated antibody.
