PrecisION™ Membrane Preparation Recombinant hERG Potassium Ion Channel by Merck
EMD Millipore's hERG membrane preparations are crude membrane preparations made from HEK293 stable recombinant cell lines, which are ideal HTS tools for screening antagonists against the hERG channel. The membrane preparations exhibit a Kd of 5.2 nM for [3H]-Astemizole. With 10 μg/well hERG Membrane Prep and 3.0 nM [3H]-Astemizole, a greater than 4-fold signal-to-background ratio was obtained.
