specificity :
This assay has high sensitivity and excellent specificity for detection of 11-Beta-Hydroxysteroid Dehydrogenase Type 1 (HSD11b1). No significant cross-reactivity or interference between 11-Beta-Hydroxysteroid Dehydrogenase Type 1 (HSD11b1) and analogues was observed.
storage stability :
For unopened kit: All the reagents should be kept according to the labels on vials. The Standard, Detection Reagent A, Detection Reagent B and the 96-well strip plate should be stored at -20 degree C upon receipt while the others should be at 4 degree C. For opened kit: When the kit is opened, the remaining reagents still need to be stored according to the above storage condition. Besides, please return the unused wells to the foil pouch containing the desiccant pack, and reseal along entire edge of zip-seal. The stability of kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition. To minimize extra influence on the performance, operation procedures and lab conditions, especially room temperature, air humidity, incubator temperature should be strictly controlled. It is also strongly suggested that the whole assay is performed by the same operator from the beginning to the end.

products description :
Principle of the Assay: The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to 11-Beta-Hydroxysteroid Dehydrogenase Type 1 (HSD11b1). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to 11-Beta-Hydroxysteroid Dehydrogenase Type 1 (HSD11b1). Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain 11-Beta-Hydroxysteroid Dehydrogenase Type 1 (HSD11b1), biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm 10nm. The concentration of 11-Beta-Hydroxysteroid Dehydrogenase Type 1 (HSD11b1) in the samples is then determined by comparing the O.D. of the samples to the standard curve.

ncbi summary :
The protein encoded by this gene is a microsomal enzyme that catalyzes the conversion of the stress hormone cortisol to the inactive metabolite cortisone. In addition, the encoded protein can catalyze the reverse reaction, the conversion of cortisone to cortisol. Too much cortisol can lead to central obesity, and a particular variation in this gene has been associated with obesity and insulin resistance in children. Mutations in this gene and H6PD (hexose-6-phosphate dehydrogenase (glucose 1-dehydrogenase)) are the cause of cortisone reductase deficiency. Alternate splicing results in multiple transcript variants encoding the same protein.[provided by RefSeq, May 2011]
uniprot summary :
HSD11B1: Catalyzes reversibly the conversion of cortisol to the inactive metabolite cortisone. Catalyzes reversibly the conversion of 7-ketocholesterol to 7-beta-hydroxycholesterol. In intact cells, the reaction runs only in one direction, from 7- ketocholesterol to 7-beta-hydroxycholesterol. Defects in HSD11B1 are a cause of cortisone reductase deficiency (CRD). In CRD, activation of cortisone to cortisol does not occur, resulting in adrenocorticotropin-mediated androgen excess and a phenotype resembling polycystic ovary syndrome (PCOS). Belongs to the short-chain dehydrogenases/reductases (SDR) family. Protein type: Membrane protein, integral; Lipid Metabolism - androgen and estrogen; EC 1.1.1.146; Oxidoreductase; Lipid Metabolism - C21-steroid hormone; Endoplasmic reticulum. Chromosomal Location of Human Ortholog: 1q32-q41. Cellular Component: endoplasmic reticulum membrane; membrane; integral to membrane. Molecular Function: 11-beta-hydroxysteroid dehydrogenase activity. Biological Process: steroid metabolic process; glucocorticoid biosynthetic process; lung development. Disease: Cortisone Reductase Deficiency 2
