Also, what sample types have been tested with this kit, and what were the reference values?

A:
Thanks for your inquiry!
CSB-EL018108HU
This kit is designed against full length. Pls refer to: https://www.uniprot.org/uniprot/Q9HBJ0.
Capture antibody is mouse monoclonal antibody and immunogen is NS0-derived recombinant protein,full length. It is Protein A/G purified;
Detection antibody is goat polyclonal antibody and immunogen is NS0-derived recombinant protein,partial. It is affinity purified.
Standard is NS0-derived recombinant protein.
We tested serum and plasma before and the test value is about 25ng/ml.
Pls let me know if you have any further questions. Thank you.

  • 功能:
    May play a role in placental development.
  • 基因功能參考文獻:
    1. The findings suggest a possible pathophysiological link between the development of Fetal growth restriction and the expression of PAPPA, PAPPA2 and PLAC-1. PMID: 29532882
    2. Screening for these five CTAs and PLAC1 by RTqPCR may offer a potentially valuable prognostic tool with good sensitivity and specificity in patients with Hepatocellular carcinoma (HCC) that may be enhanced by magneticactivated cell sorting . PMID: 28849093
    3. Study revealed that PLAC1 expression was highly expressed in non-small cell lung cancer (NSCLC) tissues, suggesting that PLAC1 may be a prognostic factor and higher risk for NSCLC patients. PLAC1 was involved in regulation of the proliferation, migration, and invasion abilities of NSCLC cells partly through regulation of epithelial-mesenchymal transition and the AKT pathway. PMID: 29138842
    4. There was no significant correlation of serum PLAC1 levels with race, age at diagnosis, body mass index (BMI) or the presence of metastatic disease. It remains to be determined whether PLAC1 serum levels can serve as a diagnostic biomarker for the presence or recurrence of disease post-surgery and/or therapy PMID: 29432428
    5. this paper shows that PLAC1 immunization does not induce infertility in mice PMID: 28351180
    6. Optimized protocol for soluble prokaryotic expression, purification and structural analysis of human placenta specific-1(PLAC1). PMID: 28315746
    7. we show that PLAC1 transcript number is significantly negatively correlated with patient survival in our samples. Thus, we suggest that characterizing tumors for TP53 mutation status, p53 protein status and PLAC1 transcription could be used to predict likely prognosis and inform treatment options in patients diagnosed with serous ovarian cancer. PMID: 28339050
    8. This study demonstrated that the protein expression of PLAC1 was significantly associated with decreased overall survival in patients with pancreatic ductal adenocarcinoma, indicating that it was a valuable prognostic marker for pancreatic ductal adenocarcinoma and might be a potential target for immunotherapy. PMID: 28618924
    9. Plac1 plays a pivotal role in the progression of HCC, and may serve as a novel therapeutic target for Hepatocellular carcinoma. PMID: 27878289
    10. PLAC1 was mainly expressed in the human villous syncytiotrophoblast (STB) layer throughout gestation, and the expression level of PLAC1 was significantly elevated during human trophoblast syncytialization. PMID: 27692364
    11. PLAC1/CP1 provides a marker for identifying gastric cancers with poor prognosis, and suggest that PLAC1/CP1 may provide a useful target for immunotherapy. PMID: 26157147

    13. Data suggests that PLAC1 plays an important role in human placental trophoblast invasion and migration. PMID: 24989904
    14. This data suggests that the Epstein-Barr virus-induced PLAC1 is a member of the cancer/testis group of tumor antigens. PMID: 24912876
    15. PLAC1/CP1 antigen is a possible prognostic marker of colorectal carcinoma, and PLAC1/CP1 p41-50 and PLAC1/CP1 p69-77 are novel HLA-A*0201-restricted CD8+ T cell epitopes PMID: 23604623
    16. NCOA3 is a selective co-activator of estrogen receptor alpha-mediated transactivation of PLAC1. PMID: 24304549
    17. we identified a novel specific antitrophoblast antibody, anti-PLAC1, in infertile women with repeated unexplained implantation failure. PLAC1 shows placenta-specific expression and is localized primarily in the syncytiotrophoblast. PMID: 23434395
    18. A novel HLA-A2-restricted cytotoxic T lymphocyte epitope from cancer-testis antigen PLAC1 has been identified in breast cancer. PMID: 21710262

    21. PLAC1, a trophoblast-specific gene, is Trophoblast-specific expression throughout gestation and responsiveness to KGF are consistent with a fundamental role for PLAC1 at the maternal-fetal interface. PMID: 12412044
    22. mRNA transcripts from placenta-expressed specific gene are detectable in maternal blood and rapidly disappear after delivery PMID: 15608456
    23. PLAC1 expression is upregulated during trophoblast differentiation, localizing primarily to the differentiated syncytiotrophoblast. PMID: 15803460

    25. In induced term pregnancies, PLAC1 mRNA in maternal blood at the beginning of the treatment correlates with time elapsed before delivery; this demonstrates that fetomaternal trafficking of nucleic acids is more consistent when labor is about to begin. PMID: 16860456
    26. Data show that PLAC1 is restricted primarily to the differentiated trophoblast, localizing to intracellular membranous compartment(s) in the apical region of the syncytiotrophoblast and associated with its apical, microvillous membrane surface. PMID: 17186554
    27. CRH, PLAC1, and selectin-P are distributed differently in preeclampsia cases compared to controls and correlate with signs of preeclampsia. PMID: 17554801
    28. RNAi-mediated silencing of PLAC1 in MCF-7 and BT-549 breast cancer cells profoundly impairs motility, migration, and invasion and induces a G1-S cell cycle block with nearly complete abrogation of proliferation. PMID: 17909063
    29. study demonstrated that PLAC1 is a novel tumor antigen with very restricted normal tissue expression; also evidence provided that PLAC1 is expressed in the tumor cells in a subset of lung cancer patients PMID: 17983203
    30. 3.8% (4/101) of HCC patients had anti-PLAC1 antibody response, suggesting the immunogenicity of PLAC1 in HCC patients. PLAC1 represents a new class of tumor associated antigen with restricted expression in placenta and cancer tissues. PMID: 18183594
    31. analysis of activation of trophoblast-specific PLAC1 in breast cancer by CCAAT/enhancer-binding protein beta (C/EBPbeta) isoform 2 PMID: 19652226
