Deoxycytidine kinase (DCK), human, recombinant

Organism: Homo sapiens (Human). Source: Yeast. Expression Region: 1-260aa. Protein Length: Full Length. Tag Info: C-terminal 6xHis-tagged. Target Protein Sequence: MATPPKRSCP SFSASSEGTR IKKISIEGNI AAGKSTFVNI LKQLCEDWEV VPEPVARWCN VQSTQDEFEE LTMSQKNGGN VLQMMYEKPE RWSFTFQTYA CLSRIRAQLA SLNGKLKDAE KPVLFFERSV YSDRYIFASN LYESECMNET EWTIYQDWHD WMNNQFGQSL ELDGIIYLQA TPETCLHRIY LRGRNEEQGI PLEYLEKLHY KHESWLLHRT LKTNFDYLQE VPILTLDVNE DFKDKYESLV EKVKEFLSTL. Purity: Greater than 90% as determined by SDS-PAGE. Endotoxin: Not test. Biological Activity: n/a. Form: Liquid or Lyophilized powder. Buffer: If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0. Reconstitution: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20 °C/-80 °C. Our default final concentration of glycerol is 50%. Customers could use it as reference. Storage: The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20 °C/-80 °C. The shelf life of lyophilized form is 12 months at -20 °C/-80 °C. Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4 °C for up to one week. Relevance: Phosphorylates the deoxyribonucleosides deoxycytidine, deoxyguanosine and deoxyadenosine. Has broad substrate specificity, and does not display selectivity based on the chirality of the substrate. It is also an essential enzyme for the phosphorylation of numerous nucleoside analogs widely employed as antiviral and chemotherapeutic agents.
