Our Abpromise guarantee covers the use of ab192980 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|Flow Cyt||Use 0.2µl for 106 cells.
ab199093 - Rabbit monoclonal IgG (Alexa Fluor® 647), is suitable for use as an isotype control with this antibody.
ab192980 staining Cytokeratin 19 in HeLa cells. The cells were fixed with 100% methanol (5 min) and then blocked in 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Triton X-100 for 1hr. The cells were then incubated with ab192980 at a working dilution of 1 in 50 (shown in red) and ab7291 (Mouse monoclonal [DM1A] to alpha Tubulin) at 1µg/ml overnight at +4°C, followed by a further incubation at room temperature for 1hr with an AlexaFluor® 488 Goat anti-mouse IgG (H&L - preadsorbed) secondary (ab150117) at 2 μg/ml (shown in green). Nuclear DNA was labelled in blue with DAPI.
This product gave a positive signal in 4% formaldehyde (10 min) fixed HeLa cells under the same testing conditions
Image was taken with a Confocal microscope (Leica micro-systems, TCS SP8).
Overlay histogram showing HeLa cells stained with ab192980 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab192980, 0.2µl/1x106 cells) for 30 min at 22ºC. Isotype control antibody (black line) was rabbit IgG (monoclonal) (Alexa Fluor® 647) (0.1μg/1x106 cells) for 30 min at 22ºC. Unlabelled sample (blue line) was also used as a control.
Acquisition of >5,000 events were collected using a 25mW red solid state diode laser (635nm) and 675/30 bandpass filter.
This antibody gave a positive signal in HeLa fixed with 4% formaldehyde (10 min)/permeabilized with 0.1% PBS-Tween for 20 min used under the same conditions.
ab192980 has not yet been referenced specifically in any publications.
