Flow cytometry using the Anti-PD-L1 antibody 332M7. Paraformaldehyde fixed MDA-MB-231 cells permeabilized with 0.5% Triton were stained with anti-unknown specificity antibody (orb256458; isotype control, black line) or the rabbit IgG version of 332M7 (orb1152460, blue line) at a dilution of 1:100 for 1h at RT. After washing, the bound antibody was detected using a goat anti-rabbit IgG AlexaFluor® 488 antibody at a dilution of 1:1000 and cells analyzed using a FACSCanto flow-cytometer.

Immunofluorescence staining of MDA-MB-231 cells with anti-PD-L1 332M7. Immunofluorescence analysis of paraformaldehyde fixed MDA-MB-231 cells stained with the chimeric rabbit IgG version of 332M7 (orb1152460) at 10 µg/ml for 1h followed by Alexa Fluor® 488 secondary antibody (2 µg/ml), showing membrane staining. The nuclear stain is DAPI (blue). Panels show from left-right, top-bottom orb1152460, DAPI, merged channels and an isotype control. The isotype control was an unknown specificity antibody (orb256458) followed by staining with Alexa Fluor® 488 secondary antibody.
