ab192841 staining Hsp47 in A431 cells. The cells were fixed with 100% methanol (5min), permeabilized in 0.1% Triton X-100 for 5 minutes and then blocked in 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated with ab192841 at a working dilution of 1 in 50 (shown in green) and ab7291 (Mouse monoclonal [DM1A] to alpha Tubulin) at 1µg/ml overnight at +4°C, followed by a further incubation at room temperature for 1h with an AlexaFluor® 594 Goat anti-Mouse secondary (ab150120) at 2μg/ml (shown in red). Nuclear DNA was labelled in blue with DAPI.This product gave a positive signal in 4% formaldehyde (10 min) fixed A431 cells under the same testing conditions.Image was taken with a confocal microscope (Leica-Microsystems, TCS SP8).
