Description

The CLDN6/9 recombinant monoclonal antibody was meticulously produced by CUSABIO following a well-defined process. B cells were isolated from the spleen of an immunized animal, with the recombinant human CLDN6/9 protein used as the immunogen during the immunization procedure. RNA was extracted from the B cells and reverse-transcribed into cDNA. The gene encoding the CLDN6/9 antibody was then extended using a degenerate primer and inserted into a vector. This recombinant vector was subsequently introduced into host cells through transfection, enabling efficient antibody expression. The CLDN6/9 recombinant monoclonal antibodies were harvested from the cell culture supernatant and purified using affinity chromatography. Extensive validation, including ELISA and FC testings, was conducted to confirm this antibody's reactivity with human CLDN6 and CLDN9 protein, ensuring its accuracy and suitability for further applications.

Gene References into Functions

Antibodies recognizing native CLDN6 as displayed on cell surfaces and mediating complement-dependent cytotoxicity were elicited in vaccinated animals. The data suggest applications of CLDN6 displaying Virus-like particles in cancer immunotherapy. PMID: 29131519
these results suggest that Helicobacter pylori lipopolysaccharide induces TLR2 expression in the gastric adenocarcinoma cells, and that the longer the exposure to lipopolysaccharide, the greater the expression of TLR2 in the cell membrane; consequently the expression of claudin-4, -6, -7 and -9 also increases PMID: 29031421
Study provides evidence that high expression of CLDN6 confers chemoresistance on breast cancer which is mediated by GSTP1, the activity of which is regulated by p53. PMID: 29116019
CLDN6 enhances the chemoresistance to ADM via activating the AF-6/ERK signaling pathway and up-regulating cancer stem cell characters in MDAMB231 cells. PMID: 29159771
we demonstrated that the downregulation of CLDN6 is regulated through promoter methylation by DNMT1, which depends on the SMAD2 pathway, and that CLDN6 is a key regulator in the SMAD2/DNMT1/CLDN6 pathway to inhibit EMT, migration and invasion of breast cancer cells PMID: 28867761
In conclusion, this information from bioinformatics analysis will help future attempts to better understand CLDN6 regulation and functions. PMID: 28656265
high expression of CLDN 6 was observed in approx. 65% of the myxofibrosarcomas, whereas the benign soft tissue tumors did not show a high expression of CLDN 6. The expression of CLDN 6 in the myxofibrosarcomas was significantly higher than those of other tumor specimens. Among the myxofibrosarcomas, the high expression of CLDN 6 was correlated with high FNCLCC grades and high AJCC stages. PMID: 28476380
Results show that DNA methylation down-regulates CLDN6 expression through MeCP2 binding to the CLDN6 promoter, deacetylating H3 and H4, and altering chromatin structure, consequently promoting migratory and invasive phenotype in breast cancer cells. PMID: 27461117
Cldn6 was decreased in alveolar type II-like epithelial cells (A549) and primary small airway epithelial cells when exposed to cigarette smoke ext PMID: 27982694

This work provides a proof of concept for the use of Claudin-6 to eliminate residual undifferentiated human pluripotent stem cells from culture. PMID: 23778593
Although claudin-6 and claudin-9 can serve as entry factors in cell lines, hepatitis C virus infection into human hepatocytes is not dependent on claudin-6 and claudin-9. PMID: 23864633
ASK1 signal may play a positive role in the inhibitory effect of claudin-6 in breast cancer. PMID: 22925655
Our results show that claudin-6 protein is significantly down-regulated in breast invasive ductal carcinomas PMID: 22455563
CLDN6 is not a specific biomarker for atypical teratoid rhabdoid tumors as it is expressed in a variety of other pediatric CNS and soft tissue tumors. PMID: 21989342
17beta-E2 might regulate the expression of claudin-6 and inhibit the proliferation and migration of MCF-7 cells. PMID: 20388399
Increased expression of claudin-6, claudin-7, or claudin-9 is sufficient to enhance tumorigenic properties of a gastric adenocarcinoma cell line. PMID: 20874001
CLDN6 may be a useful positive marker to help further identify atypical teratoid/rhabdoid tumors for diagnostic and treatment purposes PMID: 19220299
Claudins 6, 7, and 9 expressions are closely related to gastric carcinogenesis PMID: 19960275
The up-regulation of claudin-6 expression in MCF-7 breast cancer cells suppresses their malignant phenotypes with a correlation with the restoration of tight junction integrity. PMID: 20367941
claudin-6, downregulates the malignant phenotype of breast carcinoma. PMID: 20215972
Claudin 6 was not found in epithelioid glioblastomas or rhabdoid glioblastomas. PMID: 20118769
CLDN6 and CLDN9, but not CLDN1, are expressed in peripheral blood mononuclear cells, an additional site of HCV replication. PMID: 17804490
claudin-6 and claudin-9 expressed in CD81+ cells also enable the entry of HCV pseudoparticles derived from six of the major genotypes. PMID: 18234789
CLDN6, clustered with CLDN9 at human chromosome 16p13.3, is a four-transmembrane protein with WWCC motif, defined by W-X(17-22)-W-X(2)-C-X(8-10)-C. PMID: 12736707
