MB 660R NHS Ester is a fluroescent agent with a terminal NHS ester group. It is a very hydrophilic, water-soluble, far-red fluorescent dye that has a maximal absorption of 665 nm and emission at 690 nm. The NHS ester can be applied to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules.

MB 660R TFP Ester is a fluroescent agent with a terminal TFP ester group. It is a very hydrophilic, water-soluble far-red fluorescent dye that has a maximal absorption of 665 nm and emission at 690 nm. The TFP ester can react with primary amine groups and is also less susceptible to undergo hydrolysis compared to NHS ester.

MB 680R TFP Ester is a fluroescent agent with a terminal TFP ester group. It is a very hydrophilic, water-soluble far-red fluorescent dye that has a maximal absorption of 685 nm and emission at 709 nm. The compound is pH-insensitive from pH 4 to pH 10. The TFP ester can react with primary amine groups and is also less susceptible to undergo hydrolysis compared to NHS ester.

MB 680R NHS Ester is a fluroescent agent with a terminal TFP ester group. It is a very hydrophilic, water-soluble far-red fluorescent dye that has a maximal absorption of 685 nm and emission at 709 nm. The compound is pH-insensitive from pH 4 to pH 10. The NHS ester can be applied to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules.

SY-7 NHS ester is a nonfluorescent acceptor dye with a terminal NHS ester group. SY-7 NHS ester has a wide and intense quenching range from 500-600 nm that makes it useful as an acceptor in fluorescence resonance energy transfer (FRET) applications in conjunction with fluorescent dyes at 520 nm to 600 nm. The NHS ester can be applied to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules.

SY-9 NHS ester is a nonfluorescent acceptor molecule with a terminal NHS ester group. SY-9 NHS ester has a wide and intense quenching range from 500-600 nm that makes it useful as an acceptor in fluorescence resonance energy transfer (FRET) applications in conjunction with fluorescent dyes at 500 nm to 600 nm. The NHS ester can be applied to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules.

SY-21 NHS ester is a nonfluorescent acceptor dye with a terminal NHS ester group. SY-21 NHS ester has a wide and intense quenching range from 580-680 nm that makes it useful as an acceptor in fluorescence resonance energy transfer (FRET) applications in conjunction with fluorescent dyes at 580 nm to 680 nm. The NHS ester can be applied to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules.

UBQ-2 NHS Ester is a dark quencher with no native emission due to the polyaromatic-azo backbone and a terminal NHS ester. UBQ-2 NHS Ester has a wide and intense quenching range from 560-670 nm, which makes it useful as an acceptor in fluorescence resonance energy transfer (FRET) applications in conjunction with orange to far-red emitting dyes. The NHS ester can be applied to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules.

UBQ-3 DBCO is a dark quencher with no native emission due to the polyaromatic-azo backbone and a terminal DBCO group. UBQ-3 DBCO has a wide and intense quenching range from 620-730 nm makes it useful as an acceptor in fluorescence resonance energy transfer (FRET) applications in conjunction with orange to far-red emitting dyes. The DBCO group is commonly used for copper-free Click Chemistry reactions due to its strain promoted high energy.
