Western Blot: AG-2/AGR2 Antibody [NBP2-27393] - Analysis using the Azide Free version of NBP2-27393. Detection of AGR2 using AGR2 antibody. MCF7 (A), Caco-2 (B) and human stomach lysate (C) probed with AGR2 antibody at 1:100. were used for this test. The higher molecular weight band of variable intensity at ~30 kDa is uncharacterized and may represent a form of AGR2.

Background

hAG-2 and hAG-3 are recently discovered human homologues of the secreted Xenopus laevis proteins XAG-1/2 (AGR1 and AGR2) that are expressed in the cement gland, an ectodermal organ in the head associated with anteroposterior fate determination during early development (1). Although the roles of hAG-2 and hAG-3 in mammalian cells are unknown, both proteins share a high degree of protein sequence homology and lie adjacent to one another on chromosome 7p21.
