Related Product Information for anti-SRD5A1 antibody
3-oxo-5alpha-steroid 4-dehydrogenase 1 is an enzyme that in humans is encoded by the SRD5A1 gene. It is one of three forms of steroid 5alpha-reductase. The 3-oxo-5alpha-steroid 4-dehydrogenase 1 enzyme is involved in bile acid biosynthesis, androgen and estrogen metabolism. For instance, the enzyme catalyzes the conversion of testosterone into the more potent androgen, 5alpha-dihydrotestosterone. It can also catalyze the conversion of progesterone, corticosterone or other steroids, to its corresponding 5alpha-3-oxo-steroids. This chemical reaction is called 5alpha-reduction, i. e. the reduction of the delta5-4 double bond in steroids by catalyzing direct hydride transfer from NADPH to the carbon 5 position of the steroid substrate.

The SRD5A1 srd5a1 (Catalog #AAA1753597) is an Antibody produced from Rabbit and is intended for research purposes only. The product is available for immediate purchase. The Anti-SRD5A1 Antibody reacts with Human, Mouse, Rat and may cross-react with other species as described in the data sheet. AAA Biotech's SRD5A1 can be used in a range of immunoassay formats including, but not limited to, Western Blot (WB), Flow Cytometry (FC/FACS/FCM), Direct ELISA (EIA). WB: 0.1-0.25ug/ml|Mouse, Rat| FC/FACS/FCM: 1-3ug/1x106 cells|Human, Rat| Direct ELISA: 0.1-0.5ug/ml|Human|. Researchers should empirically determine the suitability of the SRD5A1 srd5a1 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "SRD5A1, Polyclonal Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.
