| In Vitro Biological Assay |
Description: | An in vitro biological assay that can be used includes the steps of (1) mixing a histone substrate (e.g., an isolated histone sample for a histone or modified histone of interest, or an isolated oligonucleosome substrate) with recombinant DOT1L enzyme (e.g., recombinant protein containing amino acids 1-416); (2) adding a candidate compound of the invention to this mixture; (3) adding non-radioactive and 3H-labeled S-Adenosyl methionine (SAM) to start the reaction; (4) adding excessive amount of non-radioactive SAM to stop the reaction; (4) washing off the free non-incorporated 3H-SAM; and (5) detecting the quantity of 3H-labeled histone substrate by any methods known in the art (e.g., by a PerkinElmer TopCount platereader). |
