| Description: | The tankyrase 1 biochemical activity of the compounds was assayed in the following assay buffer (50 mM MOPS pH7.5, 100 mM NaCl, 2.5 mM MgCl2, 0.01% Tween-20, 0.05% BSA, and 1 mM DTT) as follows: 0.25 nM of 6×HIS-tankyrase1 (1091-1325) was incubated in the presence of compound (DMSO 1.85% final) in a Perkin Elmer 384 well Proxiplate Plus (cat.no. 6008289) with 400 nM of NAD for 60 minutes at RT. The assay was then stopped with the above assay buffer containing a 0.6 μM inhibitor and the following detection components: 0.05 μg/mL monoclonal anti-PAR antibody (Trevigen cat.no. 4335-MC-01K-AC) prebound for 60 minutes with 0.63 μg/mL protein G AlphaLisa acceptor bead (Perkin Elmer cat.no. AL102M) and 5 μg/mL AlphaLisa nickel chelate donor bead (Perkin Elmer cat.no. AS 101M). The assay was incubated for 16 hours at RT in the dark and read on a Perkin Elmer Envision multi label reader using the default program set with laser excitation at 680 nM and emission at 615 nM. |
