Guanine nucleotide-binding protein G (t) subunit alpha-2 (GNAT2), bovine, recombinant

Organism: Bos taurus (Bovine). Source: E.coli. Expression Region: 2-354aa. Protein Length: Full Length of Mature Protein. Tag Info: N-terminal 6xHis-tagged. Target Protein Sequence: GSGASAEDKE LAKRSKELEK KLQEDADKEA KTVKLLLLGA GESGKSTIVK QMKIIHQDGY SPEECLEYKA IIYGNVLQSI LAIIRAMPTL GIDYAEVSCV DNGRQLNNLA DSIEEGTMPP ELVEVIRKLW KDGGVQACFD RAAEYQLNDS ASYYLNQLDR ITAPDYLPNE QDVLRSRVKT TGIIETKFSV KDLNFRMFDV GGQRSERKKW IHCFEGVTCI IFCAALSAYD MVLVEDDEVN RMHESLHLFN SICNHKFFAA TSIVLFLNKK DLFEEKIKKV HLSICFPEYD GNNSYEDAGN YIKSQFLDLN MRKDVKEIYS HMTCATDTQN VKFVFDAVTD IIIKENLKDC GLF. 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: Guanine nucleotide-binding proteins (G proteins) are involved as modulators or transducers in various transmembrane signaling systems. Transducin is an amplifier and one of the transducers of a visual impulse that performs the coupling between rhodopsin and cGMP-phosphodiesterase.
