应用举例：

Figure 1. Goat Anti-Rabbit was labeled with Lightning-Link^® 159Tb at 100 µg single reaction vial and tested with Rabbit IgG in a sandwich ELISA. Detection: Dissociation-enhanced lanthanide fluorescence.

Figure 2。 Goat Anti-Rabbit was labeled with a selection of Lightning-Link^® metal labels at 10 µg single reaction vials. 2 μg conjugates per well were run on a 4-12% Bis-Tris gel (Expedeon, NBT41212), under non-reducing conditions for 20 minutes at 50V and 1 hour at 120V in 1x MOPS (Expedeon, NXB75500). The gel was stained with InstantBlue™ (Expedeon, ISB1L) for 1 hour on the gel rocker. The gel showed no free antibody post conjugation for all conjugates except when the reaction was quenched at t=0, where no conjugation was observed.
