Protein Methods for Protein Labeling

Protein and Antibody Labeling

The Protein Methods Library has been updated to include a complete set of articles on protein and nucleic acid labeling strategies.

DyLight 550- and 650-Phosphine

Metabolic Labeling Reagents for Proteins

Thermo Scientific DyLight Fluor Phosphine Reagents are phosphine-activated fluorescent dyes for specific labeling and detection of azide-tagged molecules, which enables use of fluorescence imaging in metabolic labeling strategies now available for DyLight 550 and 650 Dyes.

DyLight 755 Reactive-Dyes

Fluorescent Labeling of Antibodies and Proteins

Thermo Scientific DyLight 755 replaces DyLight 750 as a near-IR fluor that is invisible to the naked eye but increases the staining options when using infrared imaging systems.

DyLight 550 and 650 Antibody Labeling Kits

Fluorescent Labeling Reagents for Proteins

Thermo Scientific DyLight 550 and 650 Fluors replace DyLight 540 and 649 Fluors. These new labeling reagents are available as part of our DyLight Fluor Antibody or Protein Labeling Kits, amine- or sulfhydryl-reactive dyes and secondary conjugates.
