About NCK1
The protein encoded by this gene is one of the signaling and transforming proteins containing Src homology 2 and 3 (SH2 and SH3) domains. It is located in the cytoplasm and is an adaptor protein involved in transducing signals from receptor tyrosine kinases to downstream signal recipients such as RAS. Alternatively spliced transcript variants encoding different isoforms have been found. [provided by RefSeq, Jun 2010]

About Alexa Fluor 405
Alexa Fluor™ 405 (AF405, Alexa 405) has an excitation peak at 401 nm and an emission peak at 421 nm and is similar in size, brightness and application to V450 (BD Biosciences), Vio®Blue® (Miltenyi Biotec), Cascade Blue® (ThermoFisher Scientific), Pacific Blue® (ThermoFisher Scientific). Alexa 405 is most commonly used in flow cytometery, and fluorescence microscopy applications.
