  • 緩沖液:
    Lyophilized from a 0.2 μm filtered PBS, 6% Trehalose, pH 7.4
  • 復溶:
    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℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
  • 儲存條件:
    Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
  • 保質(zhì)期:
    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.
  • 貨期:
    Basically, we can dispatch the products out in 3-7 working days after receiving your orders. Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
  • 注意事項:
    Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
  • 產(chǎn)品描述:

    This Human Claudin-9 (CLDN9) recombinant protein was produced in Mammalian cell, where the gene sequence encoding Human CLDN9 (1-217aa) was expressed with the C-terminal 10xHis tag. The activity was validated.
    In addition, this Human CLDN9 recombinant protein was developed through the Virus-Like Particles (VLPs) Platform. It is a four-pass transmembrane protein.

    CLDN9 (Claudin-9) is located on human chromosome 16p13.3, with a full length of 651 bases. The CLDN9 gene is overexpressed in the blood, pituitary and brain, and is highly expressed in endometrial cancer, liver cancer and gastric cancer cell lines. CLDN9 protein is mainly Localized at cell tight junctions, cell membranes and channel proteins.
    CLDN9 is a tight junction protein. Abnormal expression of CLDN9 will lead to impaired tight junctions function and reduced barrier function, resulting in increased tissue permeability, which will eventually lead to many diseases including hereditary, allergic diseases, infectious diseases of various systems and even tumors. Therefore, CLDN9 is regarded as a potential target for the treatment of cancer or other diseases.

5.0分 - 1 個(gè)評價(jià)


產(chǎn)品評價(jià): CLDN9被認為是治療癌癥或其他疾病的潛在靶點(diǎn)。CLDN9是一個(gè)4次跨膜的蛋白,表達全長(cháng)難度很大。CUSA Bio通過(guò)其Vlp平臺表達的重組人CLDN9蛋白,具有完整的生物活性,我使用CSB-MP005511HU產(chǎn)品及抗CLDN9抗體(CSB-RA005508MA1HU)進(jìn)行ELISA實(shí)驗,EC50為0.8032-2.566 ng/ml 。我司購買(mǎi)了CUSABIO的很多VLP產(chǎn)品,都是常規很難表達的,我們測試活性都很好,對我司的藥物及研究貢獻很大。確實(shí)是很有實(shí)力的一家公司!尤其是VLP產(chǎn)品很有特色!
