Cholesteryl ester transfer protein (CETP), human, recombinant

Organism: Homo sapiens (Human). Source: E.coli. Expression Region: 18-493aa. Protein Length: Full Length of Mature Protein. Tag Info: N-terminal MBP-tagged and C-terminal 6xHis-tagged. Target Protein Sequence: CSKGTSHEAG IVCRITKPAL LVLNHETAKV IQTAFQRASY PDITGEKAMM LLGQVKYGLH NIQISHLSIA SSQVELVEAK SIDVSIQNVS VVFKGTLKYG YTTAWWLGID QSIDFEIDSA IDLQINTQLT CDSGRVRTDA PDCYLSFHKL LLHLQGEREP GWIKQLFTNF ISFTLKLVLK GQICKEINVI SNIMADFVQT RAASILSDGD IGVDISLTGD PVITASYLES HHKGHFIYKN VSEDLPLPTF SPTLLGDSRM LYFWFSERVF HSLAKVAFQD GRLMLSLMGD EFKAVLETWG FNTNQEIFQE VVGGFPSQAQ VTVHCLKMPK ISCQNKGVVV NSSVMVKFLF PRPDQQHSVA YTFEEDIVTT VQASYSKKKL FLSLLDFQIT PKTVSNLTES SSESVQSFLQ SMITAVGIPE VMSRLEVVFT ALMNSKGVSL FDIINPEIIT RDGFLLLQMD FGFPEHLLVD FLQSLS. 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: Lectin that binds beta-galactoside and a wide array of complex carbohydrates. Plays a role in regulating apoptosis, cell proliferation and cell differentiation. Inhibits CD45 protein phosphatase activity and therefore the dephosphorylation of Lyn kinase. Strong inducer of T-cell apoptosis. Reference: "The effect of galectin-1 on the differentiation of fibroblasts and myoblasts in vitro." Goldring K., Jones G.E., Thiagarajah R., Watt D.J.
