Protein Labeling Kits for Fluorescence Detection
Protein Labeling Dyes: Excitation 350–500 nm
Blue and green fluorescent dyes for microscopy, flow cytometry, and biosensing.
This section features TurboTag™ dyes with excitation maxima between 350 and 500 nm, including well-established fluorophores such as Fluorescein (FITC), DY-405, and DY-490. These dyes emit in the blue to green range and are ideal for applications requiring high signal-to-noise ratios in the lower visible spectrum.
Recommended for fluorescence microscopy, flow cytometry panels, biosensor development, and multi-color detection assays, these dyes offer bright fluorescence, efficient NHS-ester-based conjugation, and fast purification with ZetaSpin MINI columns.
Each kit includes three ready-to-use reactions for rapid and reliable protein labeling.
TurboTag™ dyes are grouped by excitation-emission characteristics to help you quickly find the best option for your application:
Excitation 500 – 600 nm — orange and red-emitting dyes including TAMRA, ROX, and DY-554
Excitation 600 – 700 nm — far-red dyes like DY-649P1, Methylene Blue, and DY-677
Excitation 700 – 800 nm — near-infrared dyes including DY-750, DY-777, and DY-701
