How to use

In Vitro:

BRD0539 is stable in human plasma and reversibly inhibits SpCas9. BRD0539 does not interfere with the SpCas9:gRNA interaction. BRD0539 dose-dependently blocks the formation of the DNA-bound state in a dose-dependent fashion. BRD0539 impairs the perturbation induced by the 4PAM DNA. BRD0539 is able to inhibit SpCas9 in the eGFP-disruption assay.
