About Sirtuin 1
This gene encodes a member of the sirtuin family of proteins, homologs to the yeast Sir2 protein. Members of the sirtuin family are characterized by a sirtuin core domain and grouped into four classes. The functions of human sirtuins have not yet been determined; however, yeast sirtuin proteins are known to regulate epigenetic gene silencing and suppress recombination of rDNA. Studies suggest that the human sirtuins may function as intracellular regulatory proteins with mono-ADP-ribosyltransferase activity. The protein encoded by this gene is included in class I of the sirtuin family. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2008]

About Alexa Fluor 750
Alexa Fluor™ 750 (AF750, Alexa 750) has an excitation peak at 749 nm and an emission peak at 775 nm, and is spetrally similar to Cy®7 (GE Healthcare), APC-Fire™ 750 (BioLegend), CF®®750 (Biotium), DyLight™ 750 (ThermoFisher Scientific), iFluor® 750 (ATT Bioquest) and iFluor® 790 (ATT Bioquest). Alexa 750 is often used as a tandem fluorophore in flow cytometry or used on its own in fluorescence microscopy, in-vivo fluorescence microscopy or super-resolution microscopy applications.
