Abstract
Experimental results for Anti-Integrin alpha L [IPI-M17/4] (Addgene #213663) in a flow cytometry assay with a mouse sample.
Caption: Histogram from FACS analysis on ExpiCHO cells transfected with mouse integrin αLβ2 (red) or B7H3 (gray). Cells were labeled with Anti-Integrin alpha L [IPI-M17/4] (Addgene #213663) and Alexa Fluor 647 conjugated affinipure F(ab')2 Fragment Goat Anti-Rabbit IgG secondary antibody (Jackson ImmunoResearch, 111-606-046). Labeled cells were analyzed with an Intellicyt iQue Screener Plus flow cytometer.

Additional Information

Additional Information

Protocol: ExpiCHO cells were grown per manufacturer’s instruction. Mouse 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 B7H3 together with the BFP plasmid. Two days after transfection, cells at a density of 3 x 106 cells/mL were labeled with primary antibodies.

Primary antibody: 5 µg/mL in 1 mL Dulbecco's phosphate-buffered saline (DPBS), 0.5% BSA, with 0.9 mM Ca2+, 0.5 mM Mg2+, kept at 4 °C. 50 µL of antibody added to cells and incubated on ice for 30 min.

Washing conditions: Cells pelleted and washed twice in 0.5% DPBS, 0.5% BSA, with 0.9 mM Ca2+, 0.5 mM Mg2+.

Secondary antibody: 1:200 Alexa Fluor 647 F(ab')2 fragment goat anti-rabbit IgG, Fc fragment-specific (Jackson ImmunoResearch, 111-606-046) in 0.5% DPBS, 0.5% BSA, with 0.9 mM Ca2+, 0.5 mM Mg2+, 30 min, 4 °C.

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.
