Product Overview
This rabbit polyclonal antibody recognizes atrial natriuretic peptide receptor 1 (gene NPR1) in human samples and is validated for Western blot, ICC/IF and ELISA. The predicted molecular weight is 118.9 kDa, and the supplier reports an observed band at about 119 kDa.
Natriuretic peptide receptor 1 (NPR1, also called GC-A) is a transmembrane guanylyl cyclase activated by ANP and BNP. Ligand binding increases intracellular cGMP, which mediates vasodilation, natriuresis and reduced blood pressure. NPR1 is studied in cardiovascular and renal physiology and cardiac hypertrophy.

Immunogen
Recombinant human Natriuretic Peptide Receptor A/GC-A/NPR1 fragment (Ala58–Lys501), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human. UniProt places atrial natriuretic peptide receptor 1 in the membrane. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
