Product Overview
This rabbit polyclonal antibody detects glucosidase 2 subunit beta (gene PRKCSH) in human, mouse and rat samples and is validated for Western blot, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 59.4 kDa, and the supplier reports an observed band at about 90 kDa.
Glucosidase II β subunit (PRKCSH, also called hepatocystin) is the regulatory partner of the ER enzyme glucosidase II, which trims glucose residues from newly made N-linked glycans. This trimming is part of the calnexin/calreticulin quality-control cycle, and PRKCSH mutations cause autosomal dominant polycystic liver disease.

Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places glucosidase 2 subunit beta in the endoplasmic reticulum. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
