| Description: | SYK tyrosine phosphorylation activity is measured using the LANCE Technology developed by Perkin Elmer Life and Analytical Sciences (Boston, Mass.). LANCE refers to homogeneous time resolved fluorometry applications using techniques such as time-resolved fluorescence resonance energy transfer assay (TR-FRET) (see generally for procedures in Perkin Elmer Application Note How to Optimize a Tyrosine Kinase Assay Using Time Resolved Fluorescence-Based LANCE Detection, wwww.perkinelmer.com/lifesciences). The assay principle involves detection of a phosphorylated substrate using energy transfer from a phosphospecific europium-labeled antibody to streptavidin-allophycocyanin as an acceptor.To test the ability of candidate molecules to inhibit SYK tyrosine phosphorylation activity, molecules are reconstituted in 30% DMSO and serially diluted 1:3 with the final dilution containing DMSO in the absence of the candidate molecule. The final DMSO concentration in the assay is 3%. |
