zFluor™ 633 succinimidyl ester
Our zFluor™ serial dyes are developed to have the possibly highest photostability at a given wavelength compared to the other similar wavelength dyes on the market. zFluor™ 633 has almost identical spectral properties to ATTO 633, ATTO 635 and Alexa Fluor® 633 (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, zFluor™ 633 has much higher ozone stability, making it a much better choice for microarray and other biochip-based applications. In addition, zFluor™-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 iFluor® labels, the absorption and fluorescence of our zFluor™ 633 are independent of pH in the range of pH 2 to 11. It is well excited at 633 nm of He-Ne laser, the 633 nm line of the He-Ne laser.
<p>Fluorescent dye NHS esters (or succinimidyl esters) are the most popular tool for conjugating dyes to a peptide, protein, antibody, amino-modified oligonucleotide or nucleic acid. NHS esters react readily with the primary amines (R-NH<sub>2</sub>) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. The resulting dye conjugates are quite stable.</p>
