Description

SULT1A3 protein, a sulfotransferase utilizing PAPS, catalyzes the sulfate conjugation of phenolic monoamines, including neurotransmitters (dopamine, norepinephrine, serotonin) and drugs. 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 (N-His) is the recombinant human-derived SULT1A3, 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.

Biological Activity

Measured by its ability to transfer sulfate from PAPS to 1-Napthol. The specific activity is 855.567 pmol/min/μg that incubate at 37 ºC for 20 minutes.

Molecular Weight

Approximately 35 kDa.

Purity
  • Greater than 95% as determined by reducing SDS-PAGE.
Appearance

Lyophilized powder

Formulation

Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4, 8% trehalose, 8% mannitol and 0.02% Tween80.

Endotoxin Level

<1 EU/μg, determined by LAL method.

Reconstitution

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Storage & Stability

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Shipping

Room temperature in continental US; may vary elsewhere.

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
