Berthold Technologies
Berthold Technologies Mithras² LB 943 and Tristar² S LB 942 have been rigorously tested using either the Terbium Assay Application Note or the Europium Assay Application Note with demonstrated performance as shown in the setup guide.
Before using LanthaScreen Terbium and Europium Assays
Test your plate reader setup
These technical notes provide a method for verifying that a fluorescent plate reader is able to detect a change in time-resolved fluorescence energy transfer (TR-FRET) signal, confirming proper instrument set-up and a suitable response. The method is independent of any biological reaction or equilibrium and uses reagents that are on-hand for the LanthaScreen assay.
