Active Recombinant Human DNMT3B, GST-tagged

• Cat.No.: DNMT3B-165H
• Product Overview: Recombinant full-length human DNMT3B was expressed by baculovirus in Sf9 insect cells using an N-terminal GST tag.

Specification

• Species: Human
• Source: Sf9 Cells
• Tag: GST
• Description: DNMT3B or DNA (cytosine-5-)-methyltransferase 3 beta encodes a DNA methyltransferase which is thought to function in de novo methylation, rather than maintenance methylation. DNMT3B can methylate unmethylated and hemimethylated DNA with equal efficiencies. DNMT3B localizes primarily to the nucleus and its expression is developmentally regulated and is required for genome wide de novo methylation and is essential for mammalian development. Mutations in DNMT3B casue the immunodeficiency-centromeric instability-facial anomalies (ICF) syndrome.
• Form: Recombinant protein stored in 50mM Tris-HCl, pH 7.5, 50mM NaCl, 10mM glutathione, 0.1mM EDTA, 0.25mM DTT, 0.1mM PMSF, 25% glycerol.
• Bio-activity: The specific activity of DNMT3B was determined to be 525 pmol /min/mg
• Molecular Mass: ~138 kDa
• Purity: >75% by densitometry
• Applications: Methyltransferase Assay
• Storage: Store product at –70 centigrade. For optimal storage, aliquot target into smaller quantities after centrifugation and store at recommended temperature. For most favorable performance, avoid repeated handling and multiple freeze/thaw cycles.
• Concentration: 0.1 μg/μl
