The ICR 12000 is designed for ultra-high throughput ion channel screening of compound libraries, incorporating multi-channel sampling and enhanced automation features. Based upon the versatility, precision, and sensitivity of Aurora Biomed’s atomic absorption spectroscopy (AAS) instruments, the ICR 12000 is suitable for both ligand-gated and voltage-gated ion channels using cell-based flux assays. With the robustness of Aurora Biomed’s ICR technology, the reader offers high sensitivity for both electrogenic and non-electrogenic channels and transporters. The incredible 60,000 sample per day throughput of the ICR 12000 enables ion channel researchers to access compound QT liability early in the drug discovery process.

Frequently Asked Questions
The non-radioactive flux assay is considered a high throughput solution to investigate a broad range of membrane proteins including electro-neutral targets, to which conventional electrophysiology cannot be applied. The flux assay is capable of establishing the same drug potency rank orders as patch clamps.
Membrane protein targets including voltage-gated and ligand-gated ion channels, co-transporters and pumps.
Cells expressing the ion channels of interest go through a protocol of tracer loading, drug incubation, wash, treatment, and lysis before they are be fed into the ICR. The ICR can fully automate the sample analysis procedure.
The minimal sample loading volume is for 50ul for the ICR 8000 and 20ul for the ICR 12000. The ICR 12000 has a throughput of processing 60000 wells/day as compared to 5000 wells/day on the ICR 8000. The ICR 12000 also has an optional plate stacker.
