Product Overview
This rabbit polyclonal antibody detects ribosome-binding protein 1 (gene RRBP1) in human, mouse and rat samples and is validated for flow cytometry, ICC/IF, IHC and Western blot. The predicted molecular weight is 152.5 kDa, and the supplier reports an observed band at about 200 kDa.
RRBP1 (ribosome-binding protein 1, also called p180) is an integral membrane protein of the rough endoplasmic reticulum. It binds ribosomes through a large cytoplasmic domain, helping to anchor translating ribosomes to the ER and supporting the production of secreted proteins such as collagen.

Immunogen
Synthetic peptide from the C-terminal region of human RRBP1. Sequence identity with the mouse and rat orthologs: 87.2% and 89.4%, respectively.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places ribosome-binding protein 1 in the endoplasmic reticulum membrane. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
