W Human, Mouse, Rat, Monkey Endogenous 82, 84 Rabbit

Species cross-reactivity is determined by western blot.

Applications Key: W=Western Blotting


Specificity / Sensitivity

CUL3 Antibody detects endogenous levels of total Cullin-3.

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Leu750 of human Cullin-3. Antibodies are purified by protein A and peptide affinity chromatography.

Western Blotting

Western Blotting

Western blot analysis of extracts from various cell lysates, using CUL3 Antibody.


CUL3 (Cullin-3) is a member of the cullin-based ubiquitin ligase family. By interacting with Hrt1 and BTB domain containing proteins, the complex functions as a CUL3-based E3 ligase to bring specific substrates to ubiquitinylation and degradation (1). The CUL3 complex has been shown to target many substrates involved in cell cycle progression (2), transcription (3), development and differentiation (4,5).
