Our Abpromise guarantee covers the use of ab108493 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: 112 kDa).|
|ICC/IF||Use a concentration of 1 µg/ml.|
FunctionReduces the number of supercoils in a highly negatively supercoiled DNA. Essential component of the RMI complex, a complex that plays an important role in the processing of homologous recombination intermediates to limit DNA crossover formation in cells.
Tissue specificityHigh expression is found in testis, heart, skeletal muscle and pancreas.
Sequence similaritiesBelongs to the prokaryotic type I/III topoisomerase family.
Contains 1 Toprim domain.

Predicted band size: 112 kDa
Observed band size: 100 kDa why is the actual band size different from the predicted?
Additional bands at: 110 kDa, 70 kDa. We are unsure as to the identity of these extra bands.
Exposure time: 16 minutes
ab108493 stained HeLa cells. The cells were 100% methanol fixed (5 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 ab108493 at 1µg/ml overnight at +4°C. The secondary antibody (green) was DyLight® 488 goat anti- rabbit (ab96899) IgG (H+L) used at a 1/1000 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.
