ReadiLink™ Rapid trFluor™ Tb Antibody Labeling Kit
Microscale Optimized for Labeling 50 ug Antibody Per Reaction
Many biological compounds present in cells, serum or other biological fluids are naturally fluorescent, and thus the use of conventional, prompt fluorophores leads to serious limitations in assay sensitivity due to the high background caused by the autofluorescence of the biological molecules to be assayed. The use of long-lived fluorophores combined with time-resolved detection (a delay between excitation and emission detection) minimizes prompt fluorescence interferences. Our TR Fluor™ Tb probes enable time-resolved fluorometry (TRF) for the assays that require high sensitivity. These TR Fluor™ Tb probes have large Stokes shifts and extremely long emission half-lives when compared to more traditional fluorophores such as Alexa Fluor or cyanine dyes. Compared to the other TRF compounds, our TR Fluor™ Tb probes have relatively high stability, high emission yield and ability to be linked to biomolecules. Moreover, our TR Fluor™ Tb probes are insensitive to fluorescence quenching when conjugated to biological polymers such as antibodies.
<p>ReadiLink&trade; antibody labeling kits provide one of the most convenient ways to label antibodies in microscale. The kits only require two simple mixing steps without a purification step involved. Each ReadiLink&trade; antibody labeling kit provides all the essential components for performing two conjugation reactions. Each kit can be used to label monoclonal, polyclonal antibodies or other proteins with only two simple mixing steps.</p>
