Immunocytochemistry/ Immunofluorescence: Clostridium Difficile Toxin A Antibody (PCG4.1) - BSA Free [NB600-1066] - PACSIN2 is required for TcdA uptake & toxin-induced rounding in wildtype MEF cells. (C), (D) & (E). Depletion of PACSIN2 reduces TcdA uptake in MEF cells. Wildtype MEF cells expressing luciferase (luc) or PACSIN2 siRNA incubated with 50 nM TcdA-546 at 10°C for 45 min. Cells allowed to warm up to 37°C for 2 min & then washed to remove unbound toxins & incubated with fresh media prewarmed to 37°C. Bound toxins allowed to internalize for 9 min at 37°C. Cells then fixed, stained for PACSIN2 & imaged by confocal microscopy. PACSIN2 & TcdA-546 staining from each condition shown in (C). Scale bars, 10 μm. The images shown representative of multiple fields imaged from two independent experiments. (D) Comparison of mean fluorescence intensities of PACSIN2 between luc & PACSIN2 siRNA transfected cells. Data represent mean & SD of 101 individual cells. Student’s t test ***p<0.0001. (E) Comparison of mean fluorescence intensities of TcdA-546 between luc & PACSIN2 siRNA transfected cells. Data represent mean & SD of 101 individual cells. Student’s t test ***p<0.0001. Cells chosen at random for intensity analyses.

Immunocytochemistry/ Immunofluorescence: Clostridium Difficile Toxin A Antibody (PCG4.1) - BSA Free [NB600-1066] - TcdA colocalizes with PACSIN2 in wildtype MEF cells.(A) Wildtype MEFs on glass coverslips were allowed to bind 50 nM TcdA-546 for 45 min at 10°C, & cells were shifted to 37°C to allow internalization of toxin for 3 min. Cells were fixed, stained for PACSIN2, & analyzed by confocal microscopy. Merged images show PACSIN2 in red, toxin in green, & colocalization in yellow. Scale bars, 10 μm. The images shown are representative of multiple fields imaged from two independent experiments. (B) Immunofluorescence assays were performed as described in (A), but cells were stained for cav1 in addition to PACSIN2. Merged images show PACSIN2 in red, toxin in green, & cav1 in blue. Yellow puncta in merged images denote TcdA- & PACSIN2-positive structures. Pink punta denote caveolae-associated PACSIN2. Scale bars, 10 μm. (C) Pearson’s correlation coefficient to assess the extent of colocalization between PACSIN2, cav1 & TcdA-546 after 3 min toxin uptake. Data represent mean & SD of 31 individual cells chosen at random.
