Protein Labeling Kits for Fluorescence Detection
Protein Labeling Dyes: Excitation 600–700 nm
Far-red dyes for deep-tissue imaging, multiplexed detection, and enhanced signal clarity.
This section features TurboTag™ dyes with excitation maxima between 600 and 700 nm, including high-performance fluorophores such as DY-647, DY-649P1, DY-675, DY-682, and Methylene Blue. These dyes emit in the far-red region and are well-suited for applications requiring low background fluorescence and deeper tissue penetration.
TurboTag™ kits in this range are ideal for multicolor flow cytometry, in vivo imaging, immunofluorescence with low autofluorescence background, and FRET experiments. The NHS-ester-based labeling chemistry ensures stable, covalent conjugation, and the included ZetaSpin MINI columns enable rapid purification of labeled proteins with minimal hands-on time.
Each kit includes three reactions optimized for labeling proteins >25 kDa.
TurboTag™ dyes are grouped by excitation-emission characteristics to help you quickly find the best option for your application:
Excitation 350 – 500 nm — blue and green fluorophores such as Fluorescein, DY-405, DY-490
Excitation 500 – 600 nm — orange and red-emitting dyes including TAMRA, ROX, and DY-554
Excitation 700 – 800 nm — near-infrared dyes including DY-750, DY-777, and DY-701
