Chitin synthase 1 (CHS1), partial, Saccharomyces cerevisiae, recombinant

Organism: Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast). Source: E.coli. Expression Region: 4-200aa. Protein Length: Partial. Tag Info: N-terminal 6xHis-tagged. Target Protein Sequence: QNNRSRNEYH SNRKNEPSYE LQNAHSGLFH SSNEELTNRN QRYTNQNASM GSFTPVQSLQ FPEQSQQTNM LYNGDDGNNN TINDNERDIY GGFVNHHRQR PPPATAEYND VFNTNSQQLP SEHQYNNVPS YPLPSINVIQ TTPELIHNGS QTMATPIERP FFNENDYYYN NRNSRTSPSI ASSSDGYADQ EARPILE. 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: Septum formation and repair, especially under certain adverse conditions. Reference: The S. cerevisiae structural gene for chitin synthase is not required for chitin synthesis in vivo.Bulawa C.E., Slater M., Cabib E., Au-Young J., Sburlati A., Adair W.L. Jr., Robbins P.W.Cell 46:213-225(1986). Function: Septum formation and repair, especially under certain adverse conditions.
