ER beta/NR3A2 Antibody (14C8) Summary

Amino acids 1-153 of human ER-beta expressed in E. coli.
Strong Erb staining in epithelial cell nuclei. Occasional weak to moderate staining is seen in surrounding stromal and endothelial cell nuclei. Sporadic light cytoplasmic staining is sometimes observed. We have also successfully detected ERb in colon and ovarian tumors using the same antibody.
Protein G purified

Reactivity Notes

Rabbit reactivity reported in (PMID: 23664379 ). Mouse reactivity reported in scientific literature (PMID: 15750629). Please note that this antibody is reactive to Mouse and derived from the same host, Mouse. Mouse-On-Mouse blocking reagent may be needed for IHC and ICC experiments to reduce high background signal. You can find these reagents under catalog numbers PK-2200-NB and MP-2400-NB. Please contact Technical Support if you have any questions.

The human ER-beta is a newly discovered estrogen receptor initially cloned and characterized from testis. The size and structure of ER-beta is very similar to ER-alpha with the ligand and DNA binding domains being highly conserved, while the amino terminus which serves as their transactivation domains have diverged significantly. Similar in function to ER-alpha, ER-beta binds to estrogen with a high affinity and regulates estrogen specific gene activation through direct interaction with estrogen response elements (ERE's).
