Recombinant Human TOP1 Protein, His-tagged

• Cat.No.: TOP1-445H
• Product Overview: Recombinant Human TOP1(Met1~Ser250) fused with His tag at N-terminal was expressed in E. coli.

Specification

• 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.
• Source: E. coli
• Species: Human
• Tag: His
• Form: PBS, pH7.4, containing 0.01% SKL, 1mM DTT, 5% Trehalose and Proclin300.
• Molecular Mass: 34.0kDa
• Protein length: Met1~Ser250

  If bio-activity of the protein is needed, please check active protein
• Stability: The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37 centigrade for 48h, and no obvious degradation and precipitation were observed. The loss rate is less than 5% within the expiration date under appropriate storage condition.
• Storage: Avoid repeated freeze/thaw cycles. Store at 2-8 centigrade for one month. Aliquot and store at -80 centigrade for 12 months.
• Reconstitution: Reconstitute in PBS or others
