| Description: | his assay was used to determine a compound's potency in inhibiting activity of LRRK2 by determining, Kiapp, IC50, or percent inhibition values. In 384 well proxiplates F black, shallow well plates LRRK2, Eu-anti-GST-antibody, Alexa Fluor Kinase tracer 236 and test compound were incubated together. Binding of the Alexa Fluor tracer to a kinase was detected by addition of a Eu-labeled anti-GST antibody. Binding of the tracer and antibody to a kinase results in a high degree of FRET, whereas displacement of the tracer with a kinase inhibitor results in a loss of FRET. Assay conditions and materials used were as follows:Final Assay Conditions:GST-LRRK2 G2019S 10 nMEu-anti-GST-antibody 2 nMKinase tracer 236 8.5 nMKinase reaction time: 1 hourTemperature: ambientTotal volume: 15 ulDMSO 1%Materials:384 well proxiplates F black shallow well Perkin Elmer cat#6008260Kinase: LRRK2 G2019S Invitrogen cat #PV4882(LOT 567054A). |
