TRF Labeling Reagents

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.

Terbium labeling chelate for creating your own Terbium-labeled biomolecules for use in DELFIA time-resolved fluorescence (TRF) assays. The ITC-activated chelate reacts primarily with free amino groups, such as lysines.

Europium labeling chelate for creating your own Europium-labeled biomolecules for use in DELFIA time-resolved fluorescence (TRF) assays. The amino-activated chelate reacts with free carboxyl groups.

The DELFIA® Sm-Labeling kit is intended for labeling of proteins with samarium (Sm), for use in multiplexing dissociation enhanced time resolved fluoroimmunoassays.

Europium labeling chelate for creating your own Europium-labeled biomolecules for use in DELFIA time-resolved fluorescence (TRF) assays. The Iodacetamido-activated chelate reacts primarily with free sulfhydryl groups, such as cysteines.
