About CD37
The protein encoded by this gene is a member of the transmembrane 4 superfamily, also known as the tetraspanin family. Most of these members are cell-surface proteins that are characterized by the presence of four hydrophobic domains. The proteins mediate signal transduction events that play a role in the regulation of cell development, activation, growth and motility. This encoded protein is a cell surface glycoprotein that is known to complex with integrins and other transmembrane 4 superfamily proteins. It may play a role in T-cell-B-cell interactions. Alternate splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jul 2008]

About CF405S
CF®405S from Biotium is a fluorophore with an excitation peak at 404 nm and an emission peak at 431 nm. It is spectrally similar to Alexa Fluor™ 405. It can be use in fluorescence microscopy, specifically its been validated in Structured Illumination (SIM), and flow cytometry. However, in flow cytometry, superior alternatives are Brilliant™ Violet 421, SuperNova v428 and StarBright Violet 440.
