Ion Channel Screening and Profiling with Functional Assays

Creative Biogene was the leading company offering the best ion channel functional assay services. Our excellent scientists with years’ of experience and expertise will work close with your team and provide the highest quality results with the most competitive price.

Creative Biogene offers a wide range of functional assay services, including flux-based assay, fluorescence-based assays, manual patch clamp assays, and automated electrophysiological assays, etc. From single cell manual patch clamp assay service, to high throughput 384-well automated electrophysiological assays services, we provide ion channel functional assays using our cell lines on a variety of platforms and offer the throughput or depth of profiling which meet your demands.

In the past decades, it has made a great rapid progress in developing functional assays and instrumentation, enabling high throughput screening (HTS) campaigns on a broad list of channel types.

Functional cell based assays using ion flux and fluorescent assays report mechanistic effects of compounds, identifying activators, inhibitors, and allosteric modulators.

Ion flux assays are cell-based functional assays. They trace ionic flux through channels by radioisotopes, or detect ionic flux using highly sensitive flame atomic absorption spectrometers (AAS), or using fluorescence ion-specific probes/biosensors. Ion flux assays use a radioactive species in combination with a scintillation counter or use a tracer ion measured by atomic absorption/emission spectrometry.

Fluorescence assays employ membrane potential dye or FRET-based voltage senor to measure fluorescence changes caused by dye relocation in response to membrane potential depolarization or hyperpolarization following ion channel activation or inhibition.

Manual patch clamp is considered the ‘gold standard’ for assessing ion channel function. It measures biophysical and pharmacological properties of voltage-gated and ligandgated ion channels present in cells or membrane patch or tissues with unmatched temporal resolution. It provides sufficient information to assess compound effects and distinguish various modes of action, for instance, state-dependent modulation.

Over the past decade, one remarkable breakthrough in technologies for ion channel research is the development of automated electrophysiology with high throughput capability. Automated electrophysiology provides the ideal platform for supporting ion channel programs because of the high data quality achievable. Automated electrophysiology has demonstrated its robustness in generating high-quality data for all six channels selected in the CiPA proposal and provides all the information needed to determine compound effects and modes of action.
