| Preparation and Storage
|
|
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.

| Other Notes
|
|
Small volumes of SRD5a2 elisa kit vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.

MBS2023257 is a ready-to-use microwell, strip plate Double-antibody Sandwich ELISA (enzyme-linked immunosorbent assay) Kit for analyzing the presence of the Steroid 5 Alpha Reductase 2 (SRD5a2) ELISA Kit target analytes in biological samples. The concentration gradients of the kit standards or positive controls render a theoretical kit detection range of 0.156-10ng/mL in biological research samples containing SRD5a2, with an estimated sensitivity of < 0.065ng/mL. The ELISA analytical biochemical technique of the MBS2023257 kit is based on SRD5a2 antibody-SRD5a2 antigen interactions (immunosorbency) and an HRP colorimetric detection system to detect SRD5a2 antigen targets in samples. The ELISA Kit is designed to detect native, not recombinant, SRD5a2. Appropriate sample types may include undiluted body fluids and/or tissue homogenates, secretions such as Serum, Plasma, Tissue homogenates and Other Biological Fluids. Quality control assays assessing reproducibility identified the intra-assay CV (%) and inter-assay CV(%).

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 Steroid 5 Alpha Reductase 2 (SRD5a2). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Steroid 5 Alpha Reductase 2 (SRD5a2). 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 Steroid 5 Alpha Reductase 2 (SRD5a2), 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 Steroid 5 Alpha Reductase 2 (SRD5a2) in the samples is then determined by comparing the O.D. of the samples to the standard curve.

| NCBI Summary for SRD5a2
|
|
This gene encodes a microsomal protein expressed at high levels in androgen-sensitive tissues such as the prostate. The encoded protein is active at acidic pH and is sensitive to the 4-azasteroid inhibitor finasteride. Deficiencies in this gene can result in male pseudohermaphroditism, specifically pseudovaginal perineoscrotal hypospadias (PPSH). [provided by RefSeq, Jul 2008]

| UniProt Comments for SRD5a2
|
|
SRD5A2: Converts testosterone (T) into 5-alpha- dihydrotestosterone (DHT) and progesterone or corticosterone into their corresponding 5-alpha-3-oxosteroids. It plays a central role in sexual differentiation and androgen physiology. Defects in SRD5A2 are the cause of pseudovaginal perineoscrotal hypospadias (PPSH). A form of male pseudohermaphroditism in which 46,XY males show ambiguous genitalia at birth, including perineal hypospadias and a blind perineal pouch, and develop masculinization at puberty. The name of the disorder stems from the finding of a blind-ending perineal opening resembling a vagina and a severely hypospadiac penis with the urethra opening onto the perineum. Belongs to the steroid 5-alpha reductase family.
