Product Overview
This rabbit polyclonal antibody targets E3 ubiquitin-protein ligase RING1 in human and rat samples and is validated for Western blot, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 42.4 kDa, and the supplier reports an observed band at about 50 kDa.
RING1 (RING1A) is an E3 ubiquitin ligase of Polycomb repressive complex 1 (PRC1). Together with its paralog RING1B (RNF2), it adds a single ubiquitin to histone H2A at lysine 119, an epigenetic mark that helps silence developmental genes such as Hox genes and contributes to X chromosome inactivation.

Immunogen
Recombinant human RING1 fragment (Asn6–Lys387), expressed in E. coli. Sequence identity with the mouse and rat orthologs: 96.3% and 96.6%, respectively.
Reactivity Notes
The supplier lists reactivity with human and rat. UniProt places E3 ubiquitin-protein ligase RING1 in the nucleus and nucleus speckle. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
