  • 复溶：
    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.

    Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
  • 保质期：
    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.
  • 货期：
    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.
  • 注意事项：
    Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
  • 产品描述：

    This Human TPBG recombinant protein was produced in mammalian cell, where the gene sequence encoding Human TPBG (32-355aa) was expressed with the N-terminal 10xHis tag. The purity of this TPBG protein was greater than 95%. The activity was validated.

    TPBG was first discovered in embryonic development. It is highly expressed in placental trophoblast cells and is basically absent in normal tissues. It only exists in some special epithelia, such as basal stratified squamous epithelium, glandular and ductal epithelium, and retina. Secondary neurons and olfactory bulbs. Later, it was found that TPBG is expressed in many cancers, including uterine cancer, ovarian cancer, colorectal cancer, gastric cancer, kidney cancer, prostate cancer and so on. In colon, gastric, or ovarian cancer, there is evidence that the expression of TPBG is associated with low cancer cure rates. In the tissues of non-small cell lung cancer, kidney cancer or pancreatic cancer, the expression of TPBG is as high as more than 95%. Overexpression of TPBG in tumors is associated with disease progression. It may play a role in affecting the connections between tumor cells, affecting cell morphology, motility and adhesion, and then promoting distant metastasis.

  • 功能：
    May function as an inhibitor of Wnt/beta-catenin signaling by indirectly interacting with LRP6 and blocking Wnt3a-dependent LRP6 internalization.
  • 基因功能参考文献：
    1. In extravillous trophoblasts, 5T4 may function in epithelial-to-mesenchymal transition during placentation. The role of syncytiotrophoblast 5T4 is unknown, but its abundance in shed syncytial vesicles may signify route of sensitization of the maternal immune system. PMID: 28481180
    2. Collectively, these findings demonstrate that an anti-5T4 antibody-drug conjugate reduces the fraction of cancer stem cells (CSC), and prevents local recurrence and suggest a novel therapeutic approach for patients with head and neck squamous cell carcinoma. PMID: 27780858
    3. We obtained GWS evidence (P < 2.7 x 10(-6)) for gene-based association in the total sample with a novel locus, TPBG (P = 1.8 x 10(-6)). PMID: 28183528
    4. In conclusion, the present study provided evidence that TPBG is involved in PDAC metastasis, and that TPBG and its associated signaling pathways may be a suitable target for pancreatic ductal adenocarcinoma therapy. PMID: 25738465
    5. 5T4 expression is mechanistically associated with the directional movement of cells through epithelial mesenchymal transition, facilitation of CXCL12/CXCR4 chemotaxis, blocking of canonical Wnt/beta-catenin while favouring non-canonical pathway signalling PMID: 25066861
    6. Tyrosine 325 plus the leucine-rich repeat 1 surface centered on a second exposed aromatic residue, phenylalanine 97, are essential for inhibition of Wnt/beta-catenin signaling. PMID: 24582434
    7. The surface expression of 5T4 marks the use of the CXCR4 rather than the CXCR7 receptor, with distinct consequences for CXCL12 exposure. PMID: 22956548
    8. 5T4 is a potential new antigen for targeted therapies such as immunotherapy in MPM, as it is overexpressed on mesothelioma cells and recognised by 5T4-specific cytotoxic T-cells. PMID: 22498111
    9. Glycosylation and epitope mapping of the 5T4 glycoprotein oncofoetal antigen PMID: 11903056
    10. Results sugest that 5T4 is a transient marker of human embryonic stem cell differentiation & that 5T4 phenotype, colony seeding density and culture conditions influence the maintenance of pluripotent hES cells and their differentiation to neural lineages. PMID: 16616918
    11. there is a repertoire of CD8 T cell recognition of 5T4 in normal human donors and some candidate HLA-A*0201 epitopes have been identified PMID: 16646078
    12. the mRNA expression of trophoblast glycoprotein is up-regulated in cells circulating within blood from women with preeclampsia. PMID: 17978129
    13. 5T4-based cancer vaccine: cytotoxic T lymphocyte epitopes identified in Trovax-vaccinated colorectal cancer patients PMID: 18567615
    14. colorectal cancer patients who had preexisting cell proliferative responses to 5T4 were longer-term survivors PMID: 18833005

  • 亚细胞定位：
    Cell membrane; Single-pass type I membrane protein.
  • 组织特异性：
    Expressed by all types of trophoblasts as early as 9 weeks of development. Specific for trophoblastic cells except for amniotic epithelium. In adult tissues, the expression is limited to a few epithelial cell types but is found on a variety of carcinoma.
