Fluorescent Dyes  >  HiLyte™ Fluor Dyes  >>  HiLyte™ Fluor 647 acid

Product Name HiLyte™ Fluor 647 acid
Size 5 mg
Catalog # AS-81255
US$ $753
Purity ≥95% by HPLC
Description

Spectra of HiLyte™ Fluor 647 conjugates are slightly red-shifted compared to those of Cy5 dyes, resulting in an optimal match to filters designed for Cy5 dyes. However, total fluorescence of the secondary antibody conjugates of HiLyte™ Fluor 647 dyes is significantly higher than that of Cy5 conjugates supplied by other companies. Also, unlike Cy5 dyes, HiLyte™ Fluor 647 dyes have very little change in absorption or fluorescence spectra when conjugated to most proteins, oligonucleotides and nucleic acids, thus yielding greater total fluorescence at the same degree of substitution. Additionally, our in-house data indicated that HiLyte™ Fluor 647 is superior to Cy5 in fluorescence polarization-based assays. Extinction Coefficient (M-1cm-1): 250,000 Fluorescence quantum yield: 0.33 Fluorescence Life Time (ns): 1.0
