Description

To produce the CLDN18 polyclonal antibody, a rabbit was immunized with recombinant human CLDN18 protein (20-80aa). The immunogen was identified as foreign by the rabbit's immune system, triggering an immune response leading to the generation of various antibodies that target different epitopes on the antigen. Subsequently, the antibodies were collected from the rabbit's blood and subjected to antigen affinity purification, resulting in the production of the CLDN18 polyclonal antibody.

This CLDN18 antibody can react with human and rat CLDN18 proteins. CUSABIO has assessed the specificity, sensitivity, and functional activity of the CLDN18 antibody through ELISA, WB, and IHC applications.

Target Background

Function
Plays a major role in tight junction-specific obliteration of the intercellular space, through calcium-independent cell-adhesion activity.
Gene References into Functions
  1. In this study, we found downregulation of miR-767-3p and upregulation of CLDN18 in lung adenocarcinoma tissue and cell lines. PMID: 29169410
  2. CDH17 and CLDN18 are useful target molecules. Their coupling can aid in the comprehensive detection and localization of gastric cancer metastases in vivo to overcome challenges associated with intratumoral heterogeneity. PMID: 27580354
  3. Bile duct adenocarcinoma cells overexpress claudin-18 via the EGFR/RAS/ERK pathway, contributing to cell proliferation and invasion. PMID: 28624624
  4. The presented data substantiate the hypothesis that claudin-18 is a central barrier-forming component of tight junctions and show that IL-13 downregulates claudin-18. These data also suggest that the loss of claudin-18 is associated with increased sensitization to aeroantigens and airway responsiveness PMID: 27215490
  5. suggest that the reduction of CLDN5, 7, and 18 expression loses the suppressive ability of interaction between PDK1 and Akt and causes sustained phosphorylation of Akt, resulting in the disordered proliferation in lung squamous carcinoma cells PMID: 27884700
  6. Data suggest that claudin-18 suppresses the abnormal proliferation and motility of lung epithelial cells mediated by inhibition of phosphorylation of pyruvate dehydrogenase kinase isoform 1 (PDK1) and proto-oncogene protein c-akt (Akt). PMID: 26919807
  7. Human fetal lungs at 23-24 weeks gestational age, the highest-risk period for developing bronchopulmonary dysplasia, a disease of impaired alveolarization, had significantly lower CLDN18 expression relative to postnatal lungs. PMID: 24787463
  8. Evaluated expression of claudins in gastric cancer and determined their significance for patient outcome. Claudin-3 and claudin-7 were expressed in 25.4% and 29.9% of gastric cancer tissues; 51.5% of gastric cancer tissues had reduced claudin-18. PMID: 24333468
  9. High levels of CLDN18 are associated with non-small-cell lung cancer. PMID: 24710653
  10. Downregulation of miR-1303 can inhibit proliferation, migration and invasion of gastric cancer cells by targeting CLDN18. PMID: 24647998
  11. Claudin-18 positivity is a specific phenotype that is characteristic of intestinal-type Mucinous borderline tumours of the ovary PMID: 23905715
  12. Down-regulation of claudin-18 is associated with the proliferative and invasive potential of gastric cancer. PMID: 24073219
  13. rate of CLDN18.2 positivity is high in pancreatic neoplasms whereby the expression is not limited to the primaries but is also maintained upon metastasis PMID: 23900716
  14. Claudin 10/18 are most commonly expressed in lung adenocarcinomas. Female patients and non-smokers express these claudins more commonly suggesting that they may play a part in the carcinogenesis of tobacco unrelated carcinoma. PMID: 22076167
  15. Claudin 18 (a marker for early carcinogenesis) is commonly expressed in precursor lesions of pancreatic ductal adenocarcinomas. Activation of the protein kinase C pathway might be involved in claudin 18 expression associated with carcinogenesis. PMID: 21832145
  16. Cldn18 is primarily regulated at the transcriptional level via specific protein kinase C signaling pathways and modified by DNA methylation PMID: 21381080
  17. These results suggest that CLDN18 may play an important role in biliary carcinogenesis. PMID: 21607649
  18. High claudin 18 is associated with intraductal papillary mucinous neoplasms of the pancreas. PMID: 21206985
  19. We revealed that claudin-18 expression correlates with poor survival in patients with colorectal cancer and is associated with the gastric phenotype. PMID: 20846265
  20. Loss of claudin expression may enhance the grade of malignancy of gastric cancer in vivo. PMID: 17459057
  21. We conclude that Cldn-18 is the dominant claudin in the TJ of SCE and propose that the change from a Cldn-18-deficient TJ in SqE to a Cldn-18-rich TJ in SCE contributes to the greater acid resistance of BE. PMID: 17932229
  22. Indicate that the PKC/MAPK/AP-1 dependent pathway regulates claudin-18a2 expression in gastric cells. PMID: 18032479
  23. Claudin 18 and annexin A8 are frequently highly overexpressed in infiltrating ductal adenocarcinomas. PMID: 18223320
  24. Claudin 18 staining can aid in diagnosis of gastrointestinal signet ring cell carcinoma. PMID: 18580680
  25. Increased expression of claudin-18 is associated with colitis. PMID: 18831034
  26. CLDN18.2 as a novel, highly attractive pan-cancer target for the antibody therapy of epithelial tumors. PMID: 19047087
