Claudin18.2 Recombinant Rabbit Monoclonal Antibody Product Datasheet Catalog# BX50272 Clone# BP6249 Predicted Molecular Wt: 28kDa Purity: ProA affinity purified IgG Species Cross-reactivity: Human Form: Liquid Applications: IHC-P Swissprot ID: P56856-2 Background: Claudin18.2 (CLDN18.2) is a splice variant of the membrane epithelial tight junctions protein Claudin18 (CLDN18) and has been identified as a promising biomarker for targeted therapy. While upon malignant transformation, the changes in cell polarity lead to the exposure of CLDN18.2 epitopes. which are suitable for targeted therapy. Prior evidence demonstrates that except for GC, CLDN18.2 is aberrantly expressed in various primary tumors and metastases, including pancreatic, biliary, ovarian, and lung adenocarcinomas, which makes CLDN18.2 a pan-cancer target. CLDN18.2 has a restricted expression profile in normal tissues, it physiologically expresses only in the tight junction supramolecular complex of gastric mucosa.
