Claudin 18.2 (CLDN18.2) FFPE Tissue Samples

FFPE tissues for gastric and gastroesophageal junction adenocarcinoma

Claudin 18.2

Claudins (CLDN) are a family of transmembrane proteins and are present throughout the body.  Among these proteins, CLDN18.2 is the dominant isoform in normal gastric tissue, and it is often retained in malignant transformation, making it an effective biomarker for identifying previously undefined population of patients with gastric or gastroesophageal junction (G/GEJ) adenocarcinoma.
