About Chromogranin A
The protein encoded by this gene is a member of the chromogranin/secretogranin family of neuroendocrine secretory proteins. It is found in secretory vesicles of neurons and endocrine cells. This gene product is a precursor to three biologically active peptides; vasostatin, pancreastatin, and parastatin. These peptides act as autocrine or paracrine negative modulators of the neuroendocrine system. Two other peptides, catestatin and chromofungin, have antimicrobial activity and antifungal activity, respectively. Two transcript variants encoding different isoforms have been found for this gene.

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.
