By accurately defining the drug exposure levels that affect QRS duration, researchers can establish safety margins, prioritise lower-risk compounds, and reduce the chance of late-stage failures due to cardiac toxicity
Highly-validated screening assays developed by Metrion are capable of confidently identifying modulators of the lysosomal TRPML1 channel. The TRPML1 variant that lacks the endo-lysosomal retention sequences (TRPML1-4A) is used, enabling the channel to express at the plasma membrane. As such, channel behaviour can be successfully characterised by:
