Sialidase-2 (NEU2), Cricetulus griseus, recombinant

Organism: Cricetulus griseus (Chinese hamster) (Cricetulus barabensis griseus). Source: Yeast. Expression Region: 1-379aa. Protein Length: Full Length. Tag Info: N-terminal 6xHis-tagged. Target Protein Sequence: MATCPVLQKE TLFQTGDYAY RIPALIYLSK QKTLLAFAEK RLTKTDEHAD LFVLRRGSYN ADTHQVQWQA EEVVTQAYLE GHRSMSPCPL YDKQTRTLFL FFIAVRGQIS EHHQLQTGVN VTRLCHITST DHGKTWSAVQ DLTDTTIGST HQDWATFGVG PGHCLQLRNT AGSLLVPAYA YRKQPPIHAP APSAFCFLSH DHGSTWELGH FVSQNSLECQ VAEVGTGAER VVYLNARSCL GARVQAQSPN SGLDFQDNQV VSKLVEPPKG CHGSVIAFPN PTSKADALDV WLLYTHPTDS RKRTNLGVYL NQKPLDPTTW SAPTLLATGI CAYSDLQNMG HGPDGSPQFG CLYESNNYEE IVFLMFTLKQ AFPAVFGAQ. 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: Catalyzes the removal of sialic acid (N-acetylneuraminic acid) moities from glycoproteins, oligosaccharides and gangliosides.
