Notes

"The VLPs are expressed from human 293 cells (HEK293).Mix the sample gently by repeatedly pipetting it up and down. Do not vortex.Repeated freezing and thawing is not recommended.Store the protein at -20°C/-80°C upon receiving it, and ensure to avoid repeated freezing and thawing, otherwise, it will affect the protein activity. The immunization strategy should be optimized (antigen dose, regimen and adjuvant)."

Description

Claudin-6 is a tight junction protein aberrantly expressed in multiple tumor types, making it a high-priority target for therapeutic antibody development and cancer immunotherapy research. This full-length human CLDN6 (aa 1–220) is presented on virus-like particles to preserve native transmembrane topology and conformational epitopes—a critical advantage for multi-pass membrane proteins that lose proper folding when produced as soluble fragments. Functional ELISA demonstrates robust binding to multiple anti-CLDN6 recombinant antibodies with EC50 values ranging from 1.334 to 4.097 ng/mL, with empty VLPs serving as negative controls, confirming that binding is antigen-specific and supports antibody screening, epitope binning, and therapeutic candidate validation. Purity exceeding 95% by SEC-HPLC combined with endotoxin levels below 1.0 EU/μg satisfies the criteria typical for cell-based tumor metastasis assays and integrin-ligand interaction studies where endotoxin interference must be minimized.

Review: CLDN6 is an important member of the CLDN family and plays a crucial role in maintaining the function of tight junctions (TJs). CLDN6 is specifically expressed in various cancers, such as ovarian cancer, testicular cancer, hepatocellular carcinoma, and lung adenocarcinoma, and is differentially expressed in cancer cells. It is almost undetectable in normal adult tissues, making it a potential target. CLDN6 is a four-times transmembrane protein. CUSABIO expresses a full-length recombinant human CLDN6 protein through its unique VLP platform, which has good biological activity. I used the CSB-MP005508HU(A4) product for an ELISA experiment, and the EC50 was measured to be 1.726-3.525 ng/ml. The subsequent experiments progressed smoothly and were of great help to my research. I am considering continuing to purchase in large quantities!

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

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

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.

Among the myxofibrosarcomas, the high expression of CLDN 6 was correlated with high FNCLCC grades and high AJCC stages. PMID: 28476380
