The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 1 - 5 µg/ml. Predicted molecular weight: 31 kDa.
Use a concentration of 3 µg/ml.
Use 1µg for 106 cells. ab170190-Mouse monoclonal IgG1, is suitable for use as an isotype control with this antibody.
Use a concentration of 10 µg/ml.
Binds stem loop II of U1 snRNA. It is the first snRNP to interact with pre-mRNA. This interaction is required for the subsequent binding of U2 snRNP and the U4/U6/U5 tri-snRNP. In a snRNP-free form (SF-A) may be involved in coupled pre-mRNA splicing and polyadenylation process.
Belongs to the RRM U1 A/B'' family. Contains 2 RRM (RNA recognition motif) domains.
ab55751 at 10 ug/ml staining U1A in human Hella cells by Immunocytochemistry/ Immunofluorescence.
Flow Cytometry - Anti-U1A antibody (ab55751)
Overlay histogram showing HeLa cells stained with ab55751 (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 (ab55751, 1µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed.
