zFluor(TM) 647 succinimidyl ester

Ex: 648 nm. Em: 669 nm. Soluble in: DMSO. Our zFluorT serial dyes are developed to have the possibly highest photostability at a given wavelength compared to the other similar wavelength dyes on the market. zFluorT 647 has almost identical spectral properties to the popular Cy5® (GE Healthcare) and Alexa Fluor® 647 (ThermoFisher). Its high thermal and photostability makes it an excellent choice for single-molecule detection applications and high-resolution microscopy such as PALM, dSTORM and STED. Under the same test conditions, zFluorT 647 has much higher ozone stability than Cy5® and Alexa Fluor® 647, making it a much better choice for microarray and other biochip-based applications. In addition, zFluorT-labeled oligonucleotides and peptides are much brighter and more photostable than the ones labeled by Alexa Fluor® 647 and Cy5®. This feature is extremely useful for fluorescence in-situ hybridization (FISH). In common with our iFluorT labels, the absorption and fluorescence of our zFluorT 647 are independent of pH in the range of pH 2 to 11. It is well excited at 633 nm of He-Ne laser, the 647 nm line of the Krypton-Ion laser or a diode-laser emitting at 650 nm.
