Product Overview
This rabbit polyclonal antibody detects hypoxia up-regulated protein 1 (gene HYOU1) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF and ELISA. The predicted molecular weight is 111.3 kDa, and the supplier reports an observed band at about 150 kDa.
Hypoxia up-regulated protein 1 (HYOU1, also called ORP150 or GRP170) is a chaperone of the HSP70 superfamily located in the endoplasmic reticulum. It acts as a nucleotide exchange factor for BiP/GRP78, supports protein folding under stress and is induced by oxygen deprivation, so it is studied in ER stress, the unfolded protein response and cell survival under hypoxia.

Immunogen
Recombinant human ORP150/HYOU1 fragment (Lys46–Lys913), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places hypoxia up-regulated protein 1 in the endoplasmic reticulum lumen. Tissue expression noted by UniProt (human): Highly expressed in tissues that contain well-developed endoplasmic reticulum and synthesize large amounts of secretory proteins. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
