Background:
Claudin-18 (CLDN18) belongs to the large claudin family of proteins, which are tetraspan transmembrane proteins of tight junctions. Claudins exhibit specific patterns of expression in different tissues. Claudin-18 is specifically expressed in the stomach and lung. Claudin-18 has two alternatively spliced variants, Claudin-18.1 and Claudin-18.2. Claudin-18.2 is a highly selective gastric lineage marker that determines the gastric phenotype in a neoplastic condition, whereas Claudin-18.1 is lung specific. Altered Claudin-18 expression has been reported in various human malignancies, including gastric cancer, lung adenocarcinoma, and pancreatic neoplasm.
Using antibody with Fc(mutation), the background from Fc receptors will be eliminated.

Dilution factors are presented in the form of a range because the optimal dilution is a function of many factors, such as antigen density, permeability, etc. The actual dilution used must be determined empirically.
