PerkinElmer - NEV11274 - IVISense 645 MAL Fluorescent Dye (5 mg) (VivoTag)

ITEM #: 10196512
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 5 mg. Choose the right IVISense fluorescent dye for your study Product Abs/Em (nm)   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).
