Abstract
Experimental results for Anti-Integrin alpha V beta 8 [IPI-ITGAV/ITGB8.8] (Addgene Antibody 213654) in a flow cytometry assay with a human sample.
Caption: Bar diagram showing mean fluorescence intensity (MFI) from flow cytometry analysis on Expi293 cells transiently transfected with BFP and either human B7H3 (Control) or human RGD-binding integrin αVβ8 (aV/b8). Cells were labeled with rabbit chimera IPI-ITGAV/ITGB8.8 antibody (#213654) and Alexa Fluor 647-conjugated goat anti-rabbit IgG secondary antibody.

Additional Information

Additional Information

Expi293 cells were grown in Expi293 expression medium (ThermoFisher Scientific) per manufacturer’s instruction. Integrin α and β subunits were cloned in separate expression plasmids and were transiently transfected into cells together with a plasmid expressing blue fluorescent protein (BFP). Control cells were transfected with plasmid expressing full-length human B7H3 together with the BFP plasmid. Two days after transfection, the cells were labeled with the rabbit chimeric primary antibody.

Washing conditions: The cells were washed twice in 0.5% DPBS, 0.5% BSA, with 0.9 mM Ca2+, 0.5 mM Mg2+.

Detection: Labeled cells were analyzed with an Intellicyt iQue Screener Plus flow cytometer. Cells were first gated for positive BFP expression and then gated for the Alexa 647-conjugated secondary antibody.
