Sulfhydryl groups are the second most common target for modification in biological studies. They are found as exposed cysteines in protein and peptides. Sulfhydryl group biotinylation provides an advantage in some applications; for example, targeting a sulfhydryl group can help preserve the biological activity of an enzyme when amines are found at the active site.

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.

Fluorescein isothiocyanate (FITC) remains one of the most popular fluorescent labeling reagents, probably due to the low cost of the material. 5-FITC and 6-FITC have very similar absorption and fluorescence spectra. However, the isomers may differ in their binding and reactivity to proteins, and the conjugates may elute under different chromatographic conditions or migrate differently in electrophoretic gels.

Supplier: Invitrogen

The amine group is the most common target for modifying protein molecules because it is abundant in the majority of proteins either due to the presence of lysine bearing amino side chain functionality or the N-terminal-amine. Amine-reactive biotinylation reagents can be divided into two groups based on water solubility: NHS-esters and sulfo-NHS-esters.
