TRF Labeling Reagents

› ‹
OF

DELFIA labeling reagents are intended for the labeling of proteins or antibodies for use in dissociation-enhanced time-resolved fluoroimmunoassays.

Using our different DELFIA labeling reagents and kits you can now create your own custom assay.

For delayed signal measurement at a wavelength with little background interference, we offer DELFIA lanthanide chelates with both long fluorescence decay times and large Stokes' shifts.

The lanthanides in your customized labeling reagents emit a stable fluorescent signal that exhibits a sharp emission peak with high fluorescence intensity.

    DELFIA Eu-DTPA-DTA Chelate and Europium (Eu) Standard, 2 mg

    AD0024
    Europium labeling chelate for creating your own Europium-labeled biomolecules for use in DELFIA time-resolved fluorescence (TRF) assays. The DTA-activated chelate reacts with free amino groups, sulfhydryl groups, and hydroxyl groups. Because of its high reactivity, we usually do not recommend DTA as it may “inactivate” the reagent you are labeling. The DTPA chelate is more-stable than the N1 chelate.
