About Calpastatin
The protein encoded by this gene is an endogenous calpain (calcium-dependent cysteine protease) inhibitor. It consists of an N-terminal domain L and four repetitive calpain-inhibition domains (domains 1-4), and it is involved in the proteolysis of amyloid precursor protein. The calpain/calpastatin system is involved in numerous membrane fusion events, such as neural vesicle exocytosis and platelet and red-cell aggregation. The encoded protein is also thought to affect the expression levels of genes encoding structural or regulatory proteins. Alternatively spliced transcript variants encoding different isoforms have been described. [provided by RefSeq, Jun 2010]

About Alexa Fluor 594
Alexa Fluor™ 594 (AF594, Alexa 594) has an excitation peak at 590 nm and an emission peak at 617 nm, and is spectrally similar to Texas Red (ThermoFisher Scientific), DyLight™ 594 (ThermoFisher Scientific), iFluor® 594 (ATT Bioquest) and iFluor® 610 (ATT Bioquest), CF®594 (Biotium), and ATTO 594 (ATTO-TEC). Alexa 594 is commonly used for flow cytometry,fluorescence microscopy and super-resolution microscopy. It is very bright, photostable, and pH insensitive.
