| | TR-FRET Assay for LSD1 |
| Description: | LSD1 enzyme was produced in house. Tranylcypromine (TCP), LSD1 inhibitor was procured from Selleckchem. LSD1 enzyme, TCP and Biotinylated peptide substrate were diluted in assay buffer just before use. 2× inhibitor (10 μl, diluted in assay buffer) or Assay Buffer, and 5 nMenzyme were added to a 96 well plate and incubated at room temperature for 30 min. 5 μL of biotinylated Histone H3K4me1 peptide (4×) was added to each well and incubated at room temperature (RT) for 1 hour. Stop Solution containing 300 μM tranylcypromine in 1× LANCE Detection Buffer was added to the wells and incubated for 5 min at RT. Then, Detection mix containing 2 nM Eu-Ab and 50 nM ULight-Streptavidin in 1× LANCE Detection Buffer was prepared and added to the reaction mix. This mixture was incubated for 1 hour at room temperature. Readings were taken with the Pherastar Reader in TR-FRET mode (excitation at 337 nm & emission at A-665 nm, B-620 nM). |
