About Survivin
This gene is a member of the inhibitor of apoptosis (IAP) gene family, which encode negative regulatory proteins that prevent apoptotic cell death. IAP family members usually contain multiple baculovirus IAP repeat (BIR) domains, but this gene encodes proteins with only a single BIR domain. The encoded proteins also lack a C-terminus RING finger domain. Gene expression is high during fetal development and in most tumors, yet low in adult tissues. Alternatively spliced transcript variants encoding distinct isoforms have been found for this gene. [provided by RefSeq, Jun 2011]

About Alexa Fluor 680
Alexa Fluor™ 680 (AF680, Alexa 680) has an excitation peak at 679 nm and an emission peak at 702 nm, and is spectrally similar to Cy®5.5 (GE Healthcare), IR680® (Licor), iFluor® 680 (ATT Bioquest) and iFluor® 700 (ATT Bioquest). Alexa 680 is commonly used for flow cytometry, fluorescence microscopy and super-resolution microscopy.
