    HEK293 cells were transfected with RelA or empty vector and 24hrs later cell extracts harvested using a 1% CHAPS lysis buffer. Extracts were resolved by non-denaturing, non-reducing electrophoresis, transferred to nitrocellulose, and probed with a 1:500 dilution purified W6/32 . Proteins were visualized using a goat anti-mouse secondary antibody conjugated to HRP and a chemiluminescence detection system. These data document that MHC class I was upregulated in cells constitutively expressing RelA. (Data was provided by Dr. Ezra Burstein, University of Michigan Medical School, Ann Arbor, MI).

MHC class I antigens associated with β2-microglobulin are expressed by all human nucleated cells. MHC class I molecules are involved in presentation of antigens to CD8+ T cells. They play an important role in cell-mediated immune responses and tumor surveillance.

Recommended Usage

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤ 2.0 µg per 106 cells in 100 µl volume or 100 µl of whole blood. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

Clone W6/32 recognizes residues in the N terminus of the human ß2-microglobulin molecule21.

Additional reported applications (for the relevant formats) include: immunoprecipitaton2, Western blotting (non-reducing)3, immunohistochemical staining of acetone-fixed frozen tissue sections4,5, blocking6,7, inhibition of NK cell-mediated lysis10, and activation8,9. Clone W6/32 has been reported not to be suitable for immunohistochemistry on paraffin sections17. The LEAF™ purified antibody (Endotoxin < 0.1 EU/µg, Azide-Free, 0.2 µm filtered) is recommended for functional assays. For highly sensitive assays, we recommend Ultra-LEAF™ purified antibody (Cat. No. 311428) with a lower endotoxin limit than standard LEAF™ purified antibodies (Endotoxin < 0.01 EU/µg).
