Source

Human SULT1B1 / ST1B2 Protein (Human SULT1B1, His Tag) Leu 2 - Ile 296 (Accession # AAH10895) was produced in E.coli cells at ACROBiosystems.

Molecular Characterization

Human SULT1B1, His Tag is fused with a polyhistidine tag at the N-terminus, and has a calculated MW of 35.8 kDa. The predicted N-terminus is Met. DTT-reduced Protein migrates as 35.8 kDa in SDS-PAGE .

Endotoxin

Less than 1.0 EU per μg of the Human SULT1B1, His Tag by the LAL method.

Purity

>95% as determined by SDS-PAGE.

Formulation

Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 150 mM NaCl, pH 7.5. Normally Mannitol or Trehalose are added as protectants before lyophilization.

Reconstitution

See Certificate of Analysis for reconstitution instructions and specific concentrations.

Storage

Avoid repeated freeze-thaw cycles.

No activity loss was observed after storage at:
In lyophilized state for 1 year (4oC); After reconstitution under sterile conditions for 3 months (-70oC).

 

SDS-PAGE


Human SULT1B1 / ST1B2 Protein
The purity of Human SULT1B1, His Tag was determined by DTT-reduced (+) SDS-PAGE and staining overnight with Coomassie Blue.
 
 

Background

Sulfotransferase family cytosolic 1B member 1 (SULT1B1) is also known as sulfotransferase 1B2 (ST1B2) and thyroid hormone sulfotransferase, which is an enzyme that in humans is encoded by the SULT1B1 gene. Sulfotransferase enzymes catalyze the sulfate conjugation of many hormones, neurotransmitters, drugs, and xenobiotic compounds. These cytosolic enzymes are different in their tissue distributions and substrate specificities. Furthermore, sulfonation increases the water solubility of most compounds, and therefore their renal excretion, but it can also result in bioactivation to form active metabolites.
