General description
Aldo-keto reductase family 1 member C3 (UniProt: P42330; also known as EC:1.1.1.210, 17-beta-hydroxysteroid dehydrogenase type 5, 17-beta-HSD 5, 3-alpha-HSD type II brain, 3-alpha-hydroxysteroid dehydrogenase type 2, 3-alpha-HSD type 2, Chlordecone reductase homolog HAKRb, Dihydrodiol dehydrogenase 3, DD-3, DD3, Dihydrodiol dehydrogenase type I, HA1753, Prostaglandin F synthase 1, PGFS, Testosterone 17-beta-dehydrogenase 5) is encoded by the AKR1C3 (also known as DDH1, HSD17B5, KIAA0119, PGFS) gene (Gene ID: 8644) in human. AKR1C3 is a cytosolic aldo-keto reductase that catalyzes the NADH and NADPH-dependent reduction of ketosteroids to hydroxysteroids. Its expression is observed in many tissues with higher expression observed in prostate tissue and mammary glands. It acts as a NAD(P)(H)-dependent 3-, 17- and 20-ketosteroid reductase on the steroid nucleus and side chain and regulates the metabolism of androgens, estrogen, and progesterone. It displays the ability to catalyze both oxidation and reduction in vitro, but most probably acts as a reductase in vivo since the oxidase activity measured in vitro is inhibited by physiological concentration of NADPH. It is reported to reduce prostaglandin (PG) D2 to 11-β-prostaglandin F2; progesterone to 20- -hydroxyprogesterone; and estrone to 17-β-estradiol. Its activity is strongly inhibited by non-steroidal anti-inflammatory drugs (NSAID) and by low concentrations of NADPH. Two isoforms of AKR1C3 have been described that are produced by alternative splicing. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Biochem/physiol Actions
Clone 1I9 is a ZooMAb® rabbit recombinant monoclonal antibody that specifically detects Aldo-keto reductase family 1 member C3 (AKR1C3). It targets an epitope within 15 amino acids from the internal region.
Physical form
Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 µL.
Preparation Note
Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 µL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
Reconstitute lyophilized antibody pellet with 25μL of ultrapure water or Phosphate Buffered Saline (PBS). Please refer to our reconstitution protocol and the specific application guidance on the suggested starting dilutions and sample type.
