LiFluor™ 546 is a bright, orange-red fluorescent dye spectrally similar to Cy3 dye. However, compared to Cy3, LiFluor™ 546 is much brighter and more photostable. LiFluor™ 546 can be used as a replacement for Alexa Fluor 546, Cy3, TAMRA.
The NHS ester (or succinimidyl ester) is the most popular amine reactive group for labeling with the primary amines (R-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. The resulting LiFluor™ conjugate will exhibit brighter fluorescence and greater photostability than the conjugates of other spectrally similar fluorophores.
Key Features
• LiFluor™ fluorescent dye has superior brightness and good photostability.
• The dye is insensitive to pH change and has good water solubility.
• Multiplexing: across spectrum from UV to near-IR.
