About Claudin-1
Tight junctions represent one mode of cell-to-cell adhesion in epithelial or endothelial cell sheets, forming continuous seals around cells and serving as a physical barrier to prevent solutes and water from passing freely through the paracellular space. These junctions are comprised of sets of continuous networking strands in the outwardly facing cytoplasmic leaflet, with complementary grooves in the inwardly facing extracytoplasmic leaflet. The protein encoded by this gene, a member of the claudin family, is an integral membrane protein and a component of tight junction strands. Loss of function mutations result in neonatal ichthyosis-sclerosing cholangitis syndrome. [provided by RefSeq, Jul 2008]

About Brilliant Ultraviolet 395
Brilliant™ UltraViolet 395 (BUV395) is a UV-emitting base polymer dye that can be excited by the 355 nm ultraViolet laser and collected using a 379/28 bandpass filter. BUV395 has an excitation peak at 348 nm and an emission peak at 395. BUV395's fairly unique excitation and emission spectrum causes relatively little spillover into other common detectors and conflicts with very few other commonly used fluorophores. An alternative to BUV395 for flow cytometry is StarBright UltraViolet 400. This dye is part of the Brilliant™ UltraViolet dye family, developed and sold by BD Biosciences. These dyes were optimized for use with multicolor flow cytometry. BUV395 forms the backbone of the family, as all other members are tandems that use it as the acceptor, thus making them excitable by the same 355 nm UV laser.
