Our Abpromise guarantee covers the use of ab71388 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|WB||Use a concentration of 1 µg/ml. Detects a band of approximately 100 kDa (predicted molecular weight: 104 kDa).|
|ICC/IF||Use a concentration of 5 µg/ml.|
FunctionSeems to function in nuclear protein import as nuclear transport receptor. In vitro, mediates the nuclear import of splicing factor SR proteins SFRS1 and SFRS2, by recognizing phosphorylated RS domains.
Cellular localizationCytoplasm. Nucleus.

Predicted band size: 104 kDa
Observed band size: 100 kDa why is the actual band size different from the predicted?
Additional bands at: 30 kDa. We are unsure as to the identity of these extra bands.
ICC/IF image of ab71388 stained MCF7 cells. The cells were 4% paraformaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab71388, 5µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899, DyLight® 488 goat anti-rabbit IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM. This antibody also gave a positive result in 4% paraformaldehyde fixed (10 min) HeLa, Hek293 and HepG2 cells at 5µg/ml.
