Protein Labeling Kits for Fluorescence Detection
Protein Labeling Kits
TurboTag™ Protein Labeling Kits enable covalent labeling of antibodies, enzymes, and other proteins using NHS-ester chemistry. Each kit includes three dye reactions and emp BIOTECH’s pre-packed ZetaSpin MINI columns for quick purification. With a wide range of dyes spanning the visible to near-infrared spectrum (350–800 nm), TurboTag™ delivers highly pure, ready-to-use conjugates in less than 10 minutes.
Ideal for fluorescence microscopy, flow cytometry, ELISA development, and biosensor design, TurboTag™ provides consistent results with minimal hands-on time. Whether you’re working in research, diagnostics, or assay development, these kits streamline your workflow and enhance your fluorescent labeling precision.
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 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
