Label antibodies, small molecules, proteins, or peptides with IVISense NIR fluorescent dyes.
PerkinElmer’s IVISense™ fluorescent dyes (VivoTag®) for labeling antibodies, small molecules, proteins, or peptides are designed specifically to enable customized development of novel superbright fluorescent imaging agents. Dye properties, such as excellent brightness, hydrolytic stability, and photostability, as well as selection for minimal interaction with biological tissue for no potential loss of specificity, have been optimized and validated for use in in vivo or in vitro imaging.
Available as NHS esters or maleimide reactive dyes for conjugation to either free amine (-NH3) or free thiol (-SH) containing molecules. Conjugate an optimal 1-3 dyes onto your protein or choose self-quenching dyes to make your own custom fluorogenic probes.

IVISense 645 MAL fluorescent dye is a thiol (-SH, sulfhydryl) reactive maleimide-containing red fluorochrome for molecular labeling applications. This dye had been optimized and integrated for both in vivo and in vitro imaging applications. IVISense 645 MAL fluorescent dye's superior brightness makes it particularly well suited for the labeling of thiol and cysteine containing molecules for a wide range of imaging applications. The 645 nm fluorescence wavelength is ideal for biological imaging applications on in vitro and in vivo fluorescence systems. Unit size 1 mg.
|IVISense NHS FLUORESCENT DYES|
|IVISense 645 NHS||643/660||Suitable for labeling free amines (typically lysine residues)|
|IVISense 680 NHS||665/688|
|IVISense 800 NHS||785/810|
|IVISense MAL FLUORESCENT DYES|
|IVISense 645 MAL||643/660||Suitable for labeling free thiols (typically cysteine residues)|
|IVISense 680 MAL||665/688|
|IVISense SELF-QUENCHING DYES|
|IVISense 680 NHS||673/691||When a protein is labeled with multiple IVISense Self-Quenching Dye molecules, there is a shift in the absorbance of the dye, which will reduce the signal. Only choose IVISense Self-Quenching Dyes if your labeling ratio of dye: protein will be 1:1. If multiple dyes are to be conjugated onto your protein, a non-self-quenching IVISense Dye should be used. NHS dyes are suitable for labeling free amines (typically lysine residues), while MAL dyes are suitable for labeling free thiols (typically cysteine residues).|

VivoTag® 645 is a red fluorescent labeling agent containing an N-hydroxysuccinimide (NHS)-ester. Labeling reagents, such as VivoTag 645 reagent, are commonly used for labeling proteins. The NHS ester moiety on VivoTag 645 reacts with amino groups to form amide bonds. Lysines within proteins, includi ...
