Recombinant Human TOP1, His-tagged

• Cat.No.: TOP1-31198TH
• Product Overview: Recombinant fragment, corresponding to C terminal domain amino acids 651-765 of HumanTopoisomerase I with His tag expressed in a baculovirus system, approximately 14kDa.

Specification

• Species: Human
• Tag: His
• Protein Length: 651-765 a.a.
• Description: This gene encodes a DNA topoisomerase, an enzyme that controls and alters the topologic states of DNA during transcription. This enzyme catalyzes the transient breaking and rejoining of a single strand of DNA which allows the strands to pass through one another, thus altering the topology of DNA. This gene is localized to chromosome 20 and has pseudogenes which reside on chromosomes 1 and 22.
• Conjugation: HIS
• Biological activity: TOP1-31198TH contains no detectable DNA relaxation activity by itself.
• Form: Liquid
• Storage buffer: Preservative: NoneConstituents: 20% Glycerol, 20mM Tris Cl, 100mM Potassium chloride, 1mM DTT, 0.2mM EDTA, pH 8.0
• Storage: Shipped on dry ice. Upon delivery aliquot and store at -80oC. Avoid freeze / thaw cycles.
• Sequence Similarities: Belongs to the eukaryotic type I topoisomerase family.
