Product Overview
This rabbit polyclonal antibody recognizes cullin-2 (gene CUL2) in human, mouse and rat samples and is validated for ELISA, flow cytometry and Western blot. The predicted molecular weight is 87.0 kDa, and the supplier reports an observed band at about 87 kDa.
Cullin-2 (CUL2) is the scaffold of CRL2 E3 ubiquitin ligases, which use Elongin B/C and substrate adaptors carrying a VHL box. The best-known is the VHL-CUL2 ligase that targets HIF-α for degradation when oxygen is plentiful. Its activity requires neddylation, and CUL2 is studied in hypoxia signaling, protein turnover and targeted protein degradation.

Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places cullin-2 in the nucleus. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
