Descripción general

Claudin-5 is a member of claudin family. It is also known as CLDN5, beclin 1, TMVCF and CPETRL1 and is highly expressed in endothelial cells (ECs), including the blood-brain barrier.
Claudin-5 is encoded by the gene mapped to human chromosome 22q11.21.

Especificidad

Anti-Claudin-5specifically recognizes human Claudin-5.

Inmunógeno

synthetic peptide corresponding to an internal sequence of human claudin-5, conjugated to KLH. The corresponding sequence is highly conserved (single amino acid substitution) in mouse and rat claudin-5.

Aplicación

Anti-Claudin-5 antibody produced in rabbit has been used in immunofluorescence staining.
Anti-Claudin-5 antibody produced in rabbit may be used in several immunochemical techniques including immunoblotting (~23 kDa) and immunohistochemistry.

Acciones bioquímicas o fisiológicas

Claudin-5 gene is a downstream target of ETS-related gene (ERG), a transcription factor that regulates endothelial cell-restricted genes and is markedly repressed in response to inflammatory stimuli. Knockout of claudin-5 in mice is lethal, resulting in disruption of in the blood-brain barrier. Claudin-5 has been shown to be overexpressed in various tumors including lung adenocarcinomas but undetectable in squamous cells cell carcinomas.

Forma física

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

Almacenamiento y estabilidad

For continuous use, store at 2-8 °C for up to one month. For extended storage, freeze in working aliquots. Repeated freezing and thawing, or storage in “frost-free” freezers,is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilutions should be discarded if not used within 12 hours.
