|
The specificity of Claudin-5 Monoclonal Antibody (CSB0169) was tested on the Membrane Proteome Array® and shown to be specific for human Claudin-5. The Membrane Proteome Array® contains 6,000 different human membrane proteins, each expressed in unfixed human cells to ensure native conformation and post-translational modifications. The Membrane Proteome Array® represents the industry standard for determining the binding specificity of antibodies and other protein ligands. |

HEK-293F cells transiently transfected with human Claudin-5 were stained with Claudin-5 Monoclonal Antibody (CSB0169) (green) or isotype control antibody (gray), followed by AlexaFluor 647- conjugated anti-Mouse IgG secondary antibody. HEK-293F cells transiently transfected with an empty control vector were also stained with Claudin-5 Monoclonal Antibody (CSB0169) (blue). | |

Claudin-5 (CLDN5) is a member of the claudin family of integral membrane proteins, which are critical components of tight junction strands in epithelial and endothelial cells. CLDN5 is predominantly expressed in endothelial cells, especially within the blood-brain barrier, where it contributes to regulating paracellular permeability and maintaining vascular integrity. The protein spans the membrane four times and participates in cell–cell adhesion by forming tight junction complexes with other claudins. Its function is essential for the selective restriction of solutes across endothelial barriers. (NCBI Gene: 7122, UniProtKB/Swiss-Prot: O00501) Other names: TMVCF, Claudin 5, CLDN5
