Soluble (Pro)Renin Receptor ELISA Kit

INTENDED USE

Human soluble (pro)renin receptor ELISA kit is a reliable quantitative protocol for measuring soluble (pro)renin receptor (PRR, prorenin receptor) present in human serum, plasma, urine and cell culture supernatant samples. This assay has a sensitivity detection limit of 24.0 pg/ml.

BACKGROUND

Prorenin receptor (PRR) is a receptor protein which is found to be located between prorenin and renin. The binding of prorenin to PRR has the ability to achieve binding to angiotensinogen and gain catalytic activity as a result of converting angiotensinogen to ansiotensin I that is comparable to renin. It is a single transmembrane receptor protein that is 39 kDa and there is evidence that a soluble form (29kDa) can generated by cleavage of PRR with furin.

The following assay is expected to provide a new tool in the clarification and a vital marker in understanding the mechanism of many diseases. It has the ability to measure PRR in blood and urine samples. It can also measure full length PRR too, which is particular useful when samples like lysates and tissue extracts are being used.
