Deoxycorticosterone (DOC: a weak mineralocorticoid) is the precursor to corticosterone (B: the major glucocorticoid in rodents) and aldosterone. Cyp11b1 encodes 11β-hydroxylase which catalyses the conversion of DOC to B in rodents. The aim of this study is to develop sensitive and specific ELISA methods to estimate urinary DOC and B levels in mice. Antibodies against DOC and B were raised in rabbits by our laboratories as previously described and HRP-Goat anti-Rabbit IgG ...

The majority of immunoassays used to measure aldosterone (most potent mineralocorticoid) levels are still based on radio-iodinated tracer, lack sensitivity and specificity and there is a definite need for their improvement. The aim of this project is to develop a highly sensitive and specific ELISA method for urinary aldosterone estimation in samples obtained from wild type and cyp11b1 knockout mice. Antibodies against aldosterone were raised in sheep as previously described. ...
