特記事項（精製）The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific phosphopeptide. The antibody against non-phosphopeptide was removed by chromatography using non-phosphopeptide corresponding to the phosphorylation site.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
1/500 - 1/1000. Detects a band of approximately 30 kDa (predicted molecular weight: 23 kDa).
機能Plays a major role in tight junction-specific obliteration of the intercellular space.
組織特異性Expressed in kidney, lung and prostate. Isoform 1 seems to be predominant, except in some normal prostate samples, where isoform 2 is the major form. Down-regulated in breast cancers, including ductal carcinoma in situ (DCIS), lobular carcinoma in situ (LCIS) and invasive ductal carcinoma (IDC) (at protein level), as well as in several cancer cell lines. Loss of expression correlates with histological grade, occurring predominantly in high-grade lesions.
配列類似性Belongs to the claudin family.
細胞内局在Cell membrane. Lateral cell membrane. Cell junction > tight junction. Co-localizes with EPCAM at the lateral cell membrane and tight junction.
