As key components in a wide variety of biological processes involved in rapid changes in cells (e.g. cardiac/skeletal/smooth muscle contraction, and epithelial transport of nutrients), ion channels are important therapeutic targets in a range of indications, including cardiac, central nervous system, immune system and metabolic diseases. A great increase in interest of ion channels as drug targets was raised due to the recent development of successful new screening technologies.

Ion channel screening programs require strong electrophysiological support. With innovative technology platforms, our talented scientists are confident in offering high-efficiency service for your ion channel drug discovery programs with the most competitive price. Creative Bioarray can test your compounds for ion channel selectivity, develop new cell lines expressing ion channels of interest to your discovery program or validate existing ion channel-expressing cell lines. An extensive panel of ion channel screening assays with more than 80 ion channel targets and over 200 ion channel assays included are available in Creative Bioarray. To quickly and accurately provide results for drug discovery, Creative Bioarray can offer a wide range of binding or functional assays for ion channel screening analysis.

• Fluorescence assays

• Conventional patch-clamp electrophysiology

• Automated electrophysiology

Whether you are doing High Throughput Screening (HTS) or lead optimization against your target of interest, Creative Bioarray can provide a validated assay and platform fit for the purpose. A customized panel can be available consisting of any single channel or combination of channels to be tested in our flexible service. We can use your specified concentration range and assay protocol as well if desired. As a well-recognized provider in ion channel related services, Creative Bioarray is pleased to tailor the best-fit protocol to meet your specific demands and also facilitate your research and project development.

Advantages

• Comprehensive screening library: Including cardiac ion channels, central/peripheral nervous system ion channels, transporters or exchangers, etc.

• Convenience: Using automated electrophysiology will help you save compounds. For testing hERG activity, a single dose only requires less than 10μL of 10mM stock and less than 100 μL of 10 mM stock was needed in most dose-response experiments.

• Timeliness: Since time is of the essence in most drug discovery projects, we offer you high quality data in a timely fashion, thanks to our fast turnaround and guaranteed delivery.

• Flexibility：For IC₅₀ determination tests, single concentration testing or different formats of multiple concentration all depends on your program's requirement.

• Efficient electrophysiology support: Testing your compounds at Creative Bioarray will add electrophysiology support and expertise to your drug discovery programs. Creative Bioarray goes beyond the simple testing: if you need help in interpreting and making sense of the electrophysiology data, our scientists will share their expertise with you and answer your questions. We make your success our priority.

Assays

• Ion Flux Assay

• Fluorescence Assay

• Patch-clamp Technique
