Recombinant Human DNTT Protein, His-tagged

• Cat.No.: DNTT-2569H
• Product Overview: Recombinant Human DNTT(162 - 509 aa) fused with His tag at N-terminal was expressed in E. coli.

Specification

• Species: Human
• Source: E.coli
• Tag: His
• Protein Length: 162 - 509 aa
• Description: This gene is a member of the DNA polymerase type-X family and encodes a template-independent DNA polymerase that catalyzes the addition of deoxynucleotides to the 3'-hydroxyl terminus of oligonucleotide primers. In vivo, the encoded protein is expressed in a restricted population of normal and malignant pre-B and pre-T lymphocytes during early differentiation, where it generates antigen receptor diversity by synthesizing non-germ line elements (N-regions) at the junctions of rearranged Ig heavy chain and T cell receptor gene segments. Alternatively spliced transcript variants encoding different isoforms of this gene have been described.
• Form: The purified protein was Lyophilized from sterile PBS (58mM Na2HPO4,17mM NaH2PO4, 68mM NaCl, pH7.). Normally 5 % - 8 % trehalose and mannitol are added as protectants before lyophilization.

• Purity: 90%, by SDS-PAGE with Coomassie Brilliant Blue staining.
• Storage: Store for up to 12 months at -20 centigrade to -80 centigrade as lyophilized powder.
  Storage of Reconstituted Protein:
  Short-term storage: Store at 2-8 centigrade for two weeks.
  Long-term storage: Aliquot and store at -20 centigrade to -80 centigrade for up to 6 months, buffer containing 50% glycerol is recommended for reconstitution. Avoid repeat freeze-thaw cycles.
• Reconstitution: Reconstitute at 0.25 µg/μl in 200 μl sterile water for short-term storage.
  Reconstitution with 200 μl 50% glycerol solution is recommended for longer term storage (see Stability and Storage for more details).
  If a different concentration is needed for your purposes please adjust the reconstitution volume as required (please note: the ion concentration of the final solution will vary according to the volume used).
  Note: Centrifuge vial before opening. When reconstituting, gently pipet and wash down the sides of the vial to ensure full recovery of the protein into solution.
• Shipping: The product is shipped at ambient temperature. Upon receipt, store it immediately at the recommended temperature (see below).
