CHFR Antibody

CHFR is an E3 ubiquitin-protein ligase required to transiently arrest cells in early prophase when they are exposed to microtubule poisons. It acts in early prophase before chromosome condensation, when the centrosome moves apart from each other along the periphery of the nucleus. CHFR probably promotes the formation of 'Lys-63'-linked polyubiquitin chains and functions with the specific ubiquitin-conjugating UBC13-MMS2 (UBE2N-UBE2V2) heterodimer. Substrates that are polyubiquitinated at 'Lys-63' are usually not targeted for degradation, but are rather involved in signaling cellular stress. This suggests that it may be involved in signaling the presence of mitotic stress caused by microtubule poisons.

For short periods of storage (days) store at 4˚ C. For longer periods of storage, store CHFR antibody at -20˚ C. As with any antibody avoid repeat freeze-thaw cycles.

CHFR antibody can be used for detection of CHFR by ELISA at 1:312500. CHFR antibody can be used for detection of CHFR by western blot at 1 μ g/mL, and HRP conjugated secondary antibody should be diluted 1:50,000 - 100,000.
