Thioredoxin-interacting protein (TXNIP),Escherichia Coli, human, recombinant

Organism: Homo sapiens (Human). Source: E.coli. Expression Region: 1-391aa. Protein Length: Full Length. Tag Info: N-terminal 6xHis-B2M-tagged. Target Protein Sequence: MVMFKKIKSF EVVFNDPEKV YGSGEKVAGR VIVEVCEVTR VKAVRILACG VAKVLWMQGS QQCKQTSEYL RYEDTLLLED QPTGENEMVI MRPGNKYEYK FGFELPQGPL GTSFKGKYGC VDYWVKAFLD RPSQPTQETK KNFEVVDLVD VNTPDLMAPV SAKKEKKVSC MFIPDGRVSV SARIDRKGFC EGDEISIHAD FENTCSRIVV PKAAIVARHT YLANGQTKVL TQKLSSVRGN HIISGTCASW RGKSLRVQKI RPSILGCNIL RVEYSLLIYV SVPGSKKVIL DLPLVIGSRS GLSSRTSSMA SRTSSEMSWV DLNIPDTPEA PPCYMDVIPE DHRLESPTTP LLDDMDGSQD SPIFMYAPEF KFMPPPTYTE VDPCILNNNV Q. 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: ATP-dependent RNA helicase involved in mRNA export from the nucleus. Rather than unwinding RNA duplexes, DDX19B functions as a remodeler of ribonucleoprotein particles, whereby proteins bound to nuclear mRNA are dissociated and replaced by cytoplasmic mRNA binding proteins .
