Labeling Reagents

Looking for reagents to label DNA, peptides and proteins? Biosearch Technologies offers a variety of quenchers, fluorophores, and non-fluorescent modifications in the form of succinimidyl esters, carboxylic acids, amines for post-synthesis labeling.

  • Black Hole Quencher Labeling Reagents: For FRET peptide-based assays, Biosearch offers BHQ carboxylic acids, active esters and amines for coupling to amine or carboxy groups, as well as peptide resins for synthesizing BHQ dye-terminal peptides.
  • Proprietary Fluorophore Labeling Reagents: Labeling peptides with fluorophore reporters has always been fraught with limitations: poor dye selection, dye isomer contamination, inefficient dye incorporation and poor sensitivity. Our CAL Fluor® and Quasar® dyes overcome these limitations and expand your capabilities for FRET peptide assays.
  • Generic Fluorophore Labeling Reagents: Popular generic reporter dyes for protein, peptide and immunological applications.
  • Non-Fluorescent Modification Labeling Reagents: This section contains reagents for biotinylating proteins and immunological agents, and for labeling with Methylene Blue, an electrochemical reporter when conjugated to aptamers.
