| | HTRF Assay |
| Description: | Isolated TRK Enzyme assays use the HTRF KinEASE-TK kit (Cisbio Cat#62TK0PEJ) with recombinant His-tagged cytoplasmic domains of each TRK receptor sourced from Invitrogen (see table below). This activity-assay measures the phosphorylation of tyrosine residues within a substrate from the HTRF kit which has been validated by Cisbio for a variety of tyrosine kinases including the TRK receptors.Assay Details: Invitrogen Amino FAC FAC Assay ReactionTarget Cat# acids enzyme ATP TimeTRKA PV3144 aa 441-4 nM 40 uM 35 min (NTRK1) 796 TRKB PV3616 aa 526-1 nM 1.4 uM 40 min (NTRK2) 838 TRKC PV3617 aa 510- 10 nM 15 uM 30 min (NTRK3) 8250.5 mM stock solutions of test compounds are prepared and serially diluted in 100% DMSO. A standard curve using the compound of Example 135 disclosed in WO2005/116035 of 150 uM is also prepared on each test plate. High percentage effect (HPE) is defined by 150 uM. |
