Dehydrodolichyl diphosphate synthase (DHDDS), human, recombinant

Organism: Homo sapiens (Human). Source: E.coli. Expression Region: 1-333aa. Protein Length: Full Length. Tag Info: N-terminal GST-tagged. Target Protein Sequence: MSWIKEGELS LWERFCANII KAGPMPKHIA FIMDGNRRYA KKCQVERQEG HSQGFNKLAE TLRWCLNLGI LEVTVYAFSI ENFKRSKSEV DGLMDLARQK FSRLMEEKEK LQKHGVCIRV LGDLHLLPLD LQELIAQAVQ ATKNYNKCFL NVCFAYTSRH EISNAVREMA WGVEQGLLDP SDISESLLDK CLYTNRSPHP DILIRTSGEV RLSDFLLWQT SHSCLVFQPV LWPEYTFWNL FEAILQFQMN HSVLQKARDM YAEERKRQQL ERDQATVTEQ LLREGLQASG DAQLRRTRLH KLSARREERV QGFLQALELK RADWLARLGT ASA. 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: With DHDDS, forms the dehydrodolichyl diphosphate synthase (DDS) complex, an essential component of the dolichol monophosphate (Dol-P) biosynthetic machinery. Adds multiple copies of isopentenyl pyrophosphate (IPP) to farnesyl pyrophosphate (FPP) to produce dehydrodolichyl diphosphate (Dedol-PP), a precusrosor of dolichol which is utilized as a sugar carrier in protein glycosylation in the endoplasmic reticulum (ER). Regulates the glycosylation and stability of nascent NPC2, thereby promoting trafficking of LDL-derived cholesterol.
