This activity contributes significantly to inactivation and elimination, emphasizing SULT1A3's crucial role in regulating neurotransmitter and drug levels, maintaining homeostasis, and ensuring proper biological system functioning. SULT1A3 Protein, Human (His) is the recombinant human-derived SULT1A3 protein, expressed by E. coli , with N-6*His labeled tag.

Background

SULT1A3 protein, a sulfotransferase utilizing 3'-phospho-5'-adenylyl sulfate (PAPS) as its sulfonate donor, plays a pivotal role in catalyzing the sulfate conjugation of phenolic monoamines, including neurotransmitters such as dopamine, norepinephrine, and serotonin, as well as phenolic and catechol drugs. This enzymatic activity contributes significantly to the inactivation and elimination of these bioactive molecules, highlighting SULT1A3's crucial role in regulating the levels and activity of neurotransmitters and certain pharmacologically relevant compounds. The substrate specificity of SULT1A3 underscores its importance in modulating physiological responses to neurotransmitters and drugs, emphasizing its significance in maintaining homeostasis and proper functioning of biological systems.

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
