Product Overview
This rabbit polyclonal antibody detects dolichyl-diphosphooligosaccharide--protein glycosyltransferase subunit 2 (gene RPN2) in human samples and is validated for Western blot, IHC, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 69.3 kDa, and the supplier reports an observed band at about 69 kDa.
Ribophorin II (RPN2) is a subunit of the oligosaccharyltransferase complex that carries out the first step of N-linked glycosylation in the endoplasmic reticulum. It associates with the translocon so that glycans are added as proteins enter the ER, and it is studied in protein glycosylation and, in some reports, cancer drug resistance.

Immunogen
Recombinant human RPN2 fragment (Gln64–Gln174), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human. UniProt places dolichyl-diphosphooligosaccharide--protein glycosyltransferase subunit 2 in the endoplasmic reticulum and endoplasmic reticulum membrane. Tissue expression noted by UniProt (human): Expressed in all tissues tested. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
