Assay Method Information

Assay Name:  ERalpha Binding Assay
Description:  Compounds were dosed directly from a compound source microplate containing serially diluted compound (4 wells containing 10 mM, 0.1 mM, 1 mM and 10 nM final compound respectively) to an assay microplate using the Labcyte Echo 550. The Echo 550 is a liquid handler that uses acoustic technology to perform direct microplate-to-microplate transfers of DMSO compound solutions and the system can be programmed to transfer multiple small nL volumes of compound from the different source plate wells to give the desired serial dilution of compound in the assay which is then back-filled to normalise the DMSO concentration across the dilution range.In total 120 nL of compound plus DMSO were added to each well and compounds were tested in a 12-point concentration response format over a final compound concentration range of 10, 2.917, 1.042, 0.2083, 0.1, 0.0292, 0.0104, 0.002083, 0.001, 0.0002917, 0.0001042, and 0.00001 μM respectively. TR-FRET dose response data obtained with each compound was exported into a suitable software package (such as Origin or Genedata) to perform curve fitting analysis. Competitive ER alpha binding was expressed as an IC50 value. This was determined by calculation of the concentration of compound that was required to give a 50% reduction in tracer compound binding to ER alpha-LBD.
