Anti-FEM1B Antibody

FEM1B (Feminization 1 homolog B) is a substrate-recognition component of the CUL2-RING E3 ubiquitin ligase complex and a regulator of apoptosis that acts through its caspase recruitment domain. This unconjugated rabbit polyclonal reagent from Antibodies.com is supplied as a 100 µl vial and is validated for Western blot and immunohistochemistry workflows on human, mouse, and rat samples.

Investigators deploy anti-FEM1B antibodies to map expression across tissues and cell lines, to follow FEM1B-mediated protein turnover, and to study its contributions to programmed cell death pathways and androgen receptor signalling. The polyclonal format recognises multiple epitopes on the target, supporting work with denatured lysates in blotting and with formalin-fixed paraffin-embedded sections in staining protocols, while the unconjugated format leaves the antibody free for use with custom secondary reagents or label of choice.
