Alexa 647 NHS ester(Alexa Fluor 647 NHS Ester equivalent) is a bright, far-red
fluorescent dye with excitation ideally suited for the 594 nm or 633 nm laser
lines, used for cellular visualisation and labeling of antibodies, peptides,
proteins, modified oligonucleotides, and other amine-containing molecules.

Used for stable signal generation in imaging and flow cytometry, Alexa Fluor
647 dye is water soluble and pH-insensitive from pH 4 to pH 10. AF647 dye
possesses high water-solubility, high fluorescence quantum yield.

The NHS ester (or succinimidyl ester) of AF647 is the most popular tool for
conjugating this dye to a protein or antibody. NHS esters can be used to label
to the primary amines (R-NH2) of proteins, amine-modified oligonucleotides, and
other amine-containing molecules. The resulting Alexa Fluor conjugate will
exhibit brighter fluorescence and greater photostability than the conjugates of
other spectrally similar fluorophores.

AxisPharm offers 5000+ PEG Linkers with high purity. Different kinds of PEG
Reagents may be available by custom synthesis.
