Caption: Anti-Integrin beta 1 [IPI-TS2/16] (Addgene #252246) recognizes human ITGB1. Histogram from FACS analysis on ExpiCHO cells transfected with human ITGB1 (red), or B7H3 negative control (gray). Cells expressing human ITGB1 were labeled with Anti-Integrin beta 1 [IPI-TS2/16] and Alexa Fluor 647 F(ab’)2 goat anti-rabbit IgG Fc fragment (Jackson ImmunoResearch, 111-606-046). Labeled cells were analyzed with an Intellicyt iQue Screener Plus flow cytometer. Histograms were generated and normalized to mode using FlowJo™ v10.10.

Additional Information

Additional Information

EC50: A fourteen point titration of antibody concentrations, ranging from 660 nM (0.1 mg/mL) to 4.42 pM with a 1:2.5 dilution factor, against human and mouse ITGB1 showed reactivity towards human ITGB1 with an observed EC50 value of 1.88 nM.

Protocol: ExpiCHO cells were grown per manufacturer’s instruction. Plasmids expressing human ITGB1 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, cells at a density of 3 x 106 cells/mL were labeled with primary antibodies.

  • Primary antibody: 15 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: 2 µg/mL Alexa Fluor 647 F(ab')2 goat anti-rabbit IgG Fc fragment (Jackson ImmunoResearch, 111-606-046) in 0.5% DPBS, 0.5% BSA, with 0.9 mM Ca2+, 0.5 mM Mg2+, 30 min, on ice.
  • 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.
Controls
Control cells were transfected with plasmid expressing full-length human B7H3 together with the BFP plasmid.
