Renin is a secreted, 44kD glycosylated member of the peptidase A1 family.
It is an aspartyl protease that cleaves angiotensinogen to form angiotensin I.
Human Renin is synthesized as a 47kD, 383 amino acid (aa) proform (aa # 24-406).
In the kidney, pro-Renin is proteolytically cleaved after Arg66 to generate a mature enzyme.
Activity is noted for both the proform and mature enzyme when bound to a cell surface receptor.
Further processing may occur between Asn168 and Ser169 to generate 22kD, 102 aa N-terminal, and 18kD, 235 aa C-terminal fragments that are bioactive when associated.
Applications:Suitable for use in ELISA, Western Blot, Immunohistochemistry, Immunoprecipitation and Neutralization.
Other applications not tested.
Recommended Dilution:Western Blot: 0.1-0.2ug/ml with the appropriate secondary reagents to detect human Renin.
The detection limit for rhRenin is approximately 5ng/lane under non-reducing and reducing conditions
Immunohistochemistry: 3-10ug/ml.
Immunoprecipitation: Used to immunoprecipitate rhRenin from conditioned media of transfected NS0 cells.
Neutralization: Used to inhibit/neutralize the enzymatic activity of rhRenin.
The antibody was preincubated with the activated enzyme at different molar ratios at RT for 30 minutes.
The enzyme was then assayed with a fluorogenic peptide substrate.
50% of the proteolytic activity was inhibited by the antibody at approximately 40ug/ml (IC50) under conditions in which the enzyme was present at 2ug/ml and the substrate concentration was 5uM.
Considering the molecular masses of the enzyme (44kD) and the antibody (150 kD), IC50 was achieved at approximately 6:1 molar ratio of the antibody to the enzyme.
Direct ELISA: 0.5-1.0ug/ml with the appropriate secondary reagents to detect human Renin.
The detection limit for rhRenin is approximately 3ng/well
