Product Overview
| Description | Control Peptide for H9117-50G (antiserum) and H9117-50H (affinity purified) antibodies. 11-b-hydroxysteroid dehydrogenase (11b-HSD) is a microsomal short chain dehydrogenase/reductase (SDR) which catalyzes the inter-conversion of biologically active glucocorticoid (cortisol in human and corticosterone in rats and mice) and inactive glucocorticoid (cortisone and 11-dehydrocorticosterone). Two tissue specific isoforms (11b-HSD1 and 11b-HSD2) of 11b-HSD with two different functions regarding glucocorticoid availability, have been identified. The decreased 11b-hydroxy oxidation of cortisol results in Apparent Mineralocorticoid Excess (AME) disorder which is manifested by hypertension, hypokalemia, low plasma renin activity, and responsiveness to spironolactone. AME is principally a disorder of juveniles and children with this condition oxidize cortisol to cortisone poorly but carry out the reverse process unimpaired. AME arises from mutations in the 11b-HSD2 gene. The glucocorticoids can also be produced locally by 11b-HSD1 and increased visceral accumulation of glucocorticoids results in visceral obesity, insulin resistant diabetes, hyperlipidemia and hyperphagia. 11bHSD-2 (rat 400-aa, mouse 396-aa, human 405-aa) is a ~41kD glycosylated membrane-protein present in the endoplasmic reticulum (ER). The N-terminal and C-terminal (catalytic domain) of 11b-HSD2 are in the lumen and cytoplasm of ER, respectively. 11b-HSD2 irreversibly catalyzes the dehydrogenation of active 11b-hydroxycorticoids before they occupy mineralocorticoid receptors (MR) and thus confers aldosterone selectivity for inherently nonselective MR. Applications: Suitable for use in ELISA and Antibody Blocking. Not suitable for use in Western Blot. Other applications not tested. Recommended Dilution: ELISA: 50-100ng control peptide/well. Antibody Blocking: 5-10ug per 1ug H9117-50H (affinity purified) or per 1ul H9117-50G (antiserum). Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4°C for short-term only. For long-term storage, store at -20°C. Aliquots are stable for at least 6 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer. |
