The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
1/500. Detects a band of approximately 89 kDa (predicted molecular weight: 89 kDa).
1/100 - 1/250.
1/100 - 1/250.
1/30 - 1/50. ab172730-Rabbit monoclonal IgG, is suitable for use as an isotype control with this antibody.
应用说明Is unsuitable for IP.
功能Recognizes the ribosomal RNA gene promoter and activates transcription mediated by RNA polymerase I through cooperative interactions with the transcription factor SL1/TIF-IB complex. It binds specifically to the upstream control element.
Overlay histogram showing A431 cells stained with ab75781 (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 (ab75781, 1/50 dilution) for 30 min at 22°C. The secondary antibody used was Alexa Fluor® 488 goat anti-rabbit IgG (H&L) (ab150077) at 1/2000 dilution for 30 min at 22°C. Isotype control antibody (black line) was rabbit IgG (monoclonal) (1μg/1x106 cells) used under the same conditions. Unlabelled sample (blue line) was also used as a control. Acquisition of >5,000 events were collected using a 20mW Argon ion laser (488nm) and 525/30 bandpass filter.
