Organism: Homo sapiens (Human). Source: in vitro E.coli expression system. Expression Region: 1-418aa. Protein Length: Full Length. Tag Info: N-terminal 10xHis-tagged. Target Protein Sequence: MSYYGSSYHI INADAKYPGY PPEHIIAEKR RARRRLLHKD GSCNVYFKHI FGEWGSYVVD IFTTLVDTKW RHMFVIFSLS YILSWLIFGS VFWLIAFHHG DLLNDPDITP CVDNVHSFTG AFLFSLETQT TIGYGYRCVT EECSVAVLMV ILQSILSCII NTFIIGAALA KMATARKRAQ TIRFSYFALI GMRDGKLCLM WRIGDFRPNH VVEGTVRAQL LRYTEDSEGR MTMAFKDLKL VNDQIILVTP VTIVHEIDHE SPLYALDRKA VAKDNFEILV TFIYTGDSTG TSHQSRSSYV PREILWGHRF NDVLEVKRKY YKVNCLQFEG SVEVYAPFCS AKQLDWKDQQ LHIEKAPPVR ESCTSDTKAR RRSFSAVAIV SSCENPEETT TSATHEYRET PYQKALLTLN RISVESQM. Purity: Greater than 85% 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: Inward rectifier potassium channels are characterized by a greater tendency to allow potassium to flow into the cell rather than out of it. Their voltage dependence is regulated by the concentration of extracellular potassium, as external potassium is raised, the voltage range of the channel opening shifts to more positive voltages. The inward rectification is mainly due to the blockage of outward current by internal magnesium. KCNJ16 may be involved in the regulation of fluid and pH balance. In the kidney, together with KCNJ10, mediates basolateral K(+) recycling in distal tubules, this process is critical for Na(+) reabsorption at the tubules.
