  Flow Cytometry (Intracellular) - Anti-PAR2 antibody [EPR13675] (ab180953)

  Intracellular Flow Cytometry analysis of MCF-7 (human breast carcinoma) cells labeling PAR2 with unpurified ab180953 at 1/20 dilution (10ug/ml) (red). Cells were fixed with 4% paraformaldehyde and permeabilised with 90% methanol. A Goat anti rabbit IgG (Alexa Fluor^® 488) (1/2000 dilution) was used as the secondary antibody. Rabbit monoclonal IgG (Black) was used as the isotype control, cells without incubation with primary antibody and secondary antibody (Blue) were used as the unlabeled control.

  Flow Cytometry (Intracellular) - Anti-PAR2 antibody [EPR13675] (ab180953)

  Flow cytometry overlay histogram showing left HT-29 positive cells and right negative Daudi stained with ab180953 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilised with 0.1% PBS-Triton X-100 for 15 min. The cells were then incubated in 1x PBS containing 10μg/ml human IgG and 10% normal goat serum to block FC receptors and non-specific protein-protein interaction followed by the antibody (ab180953) (1x 106 in 100μl at 5.0μg/ml (1/560)) for 30min at 22°C.
  
  The secondary antibody Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) preadsorbed was incubated at 1/4000 for 30min at 22°C
  
  Isotype control antibody (black line) was Recombinant Rabbit IgG, monoclonal [EPR25A] - Isotype Control used at the same concentration and conditions as the primary antibody. Unlabelled sample (blue line) was also used as a control.
  
  Acquisition of >5000 events were collected using a 50 mW Blue laser (488nm) and 525/40 bandpass filter.

  PAR-2 gene and protein expression after 48 h of PAR-2 or scrambled siRNA transfection in human corneal epithelial cells. (A) PAR-2 gene expression in HCE-T cells transfected with PAR-2 or scrambled siRNA. PAR-2 gene expression was normalized to expression of the endogenous gene, GAPDH (n = 3 samples/group; (B) PAR-2 bands measured by Western Blot in lysates from human corneal epithelial cells transfected with PAR-2 or scrambled siRNA; (C) PAR-2 band intensity in human corneal epithelial cells transfected with PAR-2 or scrambled siRNA. The intensity signal of PAR-2 band was normalized to the band intensity of GAPDH and designated as 100% for scrambled siRNA-treated cells (n = 5 samples/group); (D) PAR-2 protein expression in HCE-T cells transfected with PAR-2 or scrambled siRNA as determined by ELISA. PAR-2 protein expression was normalized to total protein in lysates (n = 3 samples in PAR-2 siRNA transfected and n = 2 in scrambled siRNA transfected, * p ≤ 0.05, *** p ≤ 0.001 data are represented as mean ± SEM, and a two-tailed, unpaired Student’s t-test was used to compare PAR-2 siRNA transfected to scrambled siRNA transfected cells).
