DHRS9 Protein, Human (His)

Cat. No.: HY-P76871
Handling Instructions

DHRS9 Protein, a 3-alpha-hydroxysteroid dehydrogenase, converts 3-alpha-tetrahydroprogesterone to dihydroxyprogesterone and 3-alpha-androstanediol to dihydroxyprogesterone, supported by studies. Additionally, DHRS9 significantly contributes to retinoic acid biosynthesis from retinaldehyde, utilizing both NADH and NADPH as coenzymes in its reactions. DHRS9 Protein, Human (His) is the recombinant human-derived DHRS9 protein, expressed by E. coli, with N-His labeled tag. The total length of DHRS9 Protein, Human (His) is 302 a.a., with molecular weight of ~34 kDa.

Background

The DHRS9 protein is a 3-alpha-hydroxysteroid dehydrogenase that performs the conversion of 3-alpha-tetrahydroprogesterone (allopregnanolone) to dihydroxyprogesterone and 3-alpha-androstanediol to dihydroxyprogesterone. This enzymatic activity has been supported by studies. Furthermore, DHRS9 also plays a significant role in the biosynthesis of retinoic acid from retinaldehyde, as evidenced by research. Notably, this protein has the ability to utilize both NADH and NADPH as coenzymes in its enzymatic reactions.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

  • Specific Activity Calculator

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
× = ×

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
