G-protein coupled receptor 157 (GPR157), human, recombinant

Organism: Homo sapiens (Human). Source: in vitro E.coli expression system. Expression Region: 1-335aa. Protein Length: Full Length. Tag Info: N-terminal 10xHis-tagged. Target Protein Sequence: MQPSPPPTEL VPSERAVVLL SCALSALGSG LLVATHALWP DLRSRARRLL LFLSLADLLS AASYFYGVLQ NFAGPSWDCV LQGALSTFAN TSSFFWTVAI ALYLYLSIVR AARGPRTDRL LWAFHVVSWG VPLVITVAAV ALKKIGYDAS DVSVGWCWID LEAKDHVLWM LLTGKLWEML AYVLLPLLYL LVRKHINRAH TALSEYRPIL SQEHRLLRHS SMADKKLVLI PLIFIGLRVW STVRFVLTLC GSPAVQTPVL VVLHGIGNTF QGGANCIMFV LCTRAVRTRL FSLCCCCCSS QPPTKSPAGT PKAPAPSKPG ESQESQGTPG ELPST. 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: Orphan receptor that promotes neuronal differentiation of radial glial progenitors (RGPs). The activity of this receptor is mediated by a G(q)-protein that activates a phosphatidylinositol-calcium second messenger. Reference: "Complete coding sequence of GPR157."
