Selenide, water dikinase 1 (SEPHS1), human, recombinant

Organism: Homo sapiens (Human). Source: E.coli. Expression Region: 1-392aa. Protein Length: Full Length. Tag Info: N-terminal GST-tagged. Target Protein Sequence: STRESFNPES YELDKSFRLT RFTELKGTGC KVPQDVLQKL LESLQENHFQ EDEQFLGAVM PRLGIGMDTC VIPLRHGGLS LVQTTDYIYP IVDDPYMMGR IACANVLSDL YAMGVTECDN MLMLLGVSNK MTDRERDKVM PLIIQGFKDA AEEAGTSVTG GQTVLNPWIV LGGVATTVCQ PNEFIMPDNA VPGDVLVLTK PLGTQVAVAV HQWLDIPEKW NKIKLVVTQE DVELAYQEAM MNMARLNRTA AGLMHTFNAH AATDITGFGI LGHAQNLAKQ QRNEVSFVIH NLPVLAKMAA VSKACGNMFG LMHGTCPETS GGLLICLPRE QAARFCAEIK SPKYGEGHQA WIIGIVEKGN RTARIIDKPR IIEVAPQVAT QNVNPTPGAT S. 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: Synthesizes selenophosphate from selenide and ATP. Reference: "Human selenophosphate synthetase 1 has five splice variants with unique interactions, subcellular localizations and expression patterns."
