Most cancer cells showed moderate cytoplasmic staining. Urothelial cancers as well as several pancreatic, liver and colorectal cancers were strongly stained. Gliomas and lymphomas were weakly stained or negative.
Weak to moderate cytoplasmic positivity was observed in most cancers. Colorectal cancers were strongly stained while melanomas, skin and testicular cancers were weakly stained or negative.
Cancer cells displayed moderate to strong cytoplasmic immunoreactivity.

Ribophorin II (HGNC Symbol)
Entrez gene summary
This gene encodes a type I integral membrane protein found only in the rough endoplasmic reticulum. The encoded protein is part of an N-oligosaccharyl transferase complex that links high mannose oligosaccharides to asparagine residues found in the Asn-X-Ser/Thr consensus motif of nascent polypeptide chains. This protein is similar in sequence to the yeast oligosaccharyl transferase subunit SWP1. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.
