Protein Linking and Labeling Systems

Protein linking and labeling systems provide a convenient means for attaching fluorescent labels or biotins to antibodies and larger proteins. These kits are ideal for use with multiple applications, including flow cytometry, fluorescent microscopy, immunohistochemistry, primary detection, ELISAs, immunocytochemistry, and FISH. These systems are available with a variety of dye colors, biotin, fluorescent agents, and all the components needed to perform multiple conjugations and purifications. Protein labeling follows a simple protocol of reaction, separation, and then use.

Pierce™ DyLight™ PEGylated Dyes, Antibody Labelling Dyes, Thermo Scientific

Pierce™ DyLight™ PEGylated Dyes, Antibody Labelling Dyes, Thermo Scientific

Supplier: Thermo Scientific

DyLight™ PEGylated dyes display absorption spectra ranging from 550 nm to 783 nm. These reagents fluoresce over a broad pH range, are more intense than Alexa Fluor® or Cy® dyes in many applications and match the output wavelengths of common fluorescence instrumentation. Additionally, the water solubility of the DyLight™ reagents allows a high dye-to-protein ratio without precipitation during conjugation.

Pierce EZ-Link® Carboxyl Reactive Biotinylation Reagents, Thermo Scientific

Pierce EZ-Link® Carboxyl Reactive Biotinylation Reagents, Thermo Scientific

Supplier: Thermo Scientific

Carboxyl groups, in the form of carboxy termini, aspartate residues or glutamate residues, can be targeted for biotin labeling using amine-derivatized biotin molecules. This reaction is mediated by a class of crosslinkers known as carbodiimides and results in the formation of an amide bond. The reaction with EDC, the most common carbodiimide crosslinker, is generally performed in an MES buffer at pH 4.5 - 5 and requires just minutes to complete.
