About ALK-1
This gene encodes a type I cell-surface receptor for the TGF-beta superfamily of ligands. It shares with other type I receptors a high degree of similarity in serine-threonine kinase subdomains, a glycine- and serine-rich region (called the GS domain) preceding the kinase domain, and a short C-terminal tail. The encoded protein, sometimes termed ALK1, shares similar domain structures with other closely related ALK or activin receptor-like kinase proteins that form a subfamily of receptor serine/threonine kinases. Mutations in this gene are associated with hemorrhagic telangiectasia type 2, also known as Rendu-Osler-Weber syndrome 2. [provided by RefSeq, Jul 2008]

About DyLight 405
DyLight™ 405 has an excitation peak at 400 nm and an emission peak at 420 nm and is spectrally similar to Alexa Fluor™ 405 and Cascade Blue. DyLight™ 405 is most commonly used in flow cytometery and fluorescence microscopy applications.
