AssayQuant’s mission is to support the development of more effective therapies for cancer, chronic inflammation, neurodegeneration, and other serious conditions. Our team is motivated by a shared vision of reducing suffering, to build a healthier world. We stand with you at the frontier of target biology and drug discovery & development, helping you to rapidly and effectively identify the best solutions, from the vast number of possibilities.

A Powerful Approach for Understanding Kinase and Phosphatase Function and Identifying the Most Effective Drugs

AssayQuant's Proprietary PhosphoSens® Technology uses novel, fluorogenic sensors in enzyme recognition sequences that are carefully optimized for each enzyme to relay quantitative information on phosphorylation in real time with less effort.

  • Our direct, real-time, kinetic, enzyme activity assays yield better, more reliable data than other methods, enabling better decisions regarding target biology and generation of lead candidates to empower faster movement through the drug discovery process.
  • Whether used in high, moderate or low throughput modes, the resulting richer information from quantitative data allows you to rapidly rank candidates by inhibition mechanism, selectivity profiling and multiple measures of potency, with covalent and reversible inhibitors and fragments.
  • AssayQuant has a catalog of over four hundred optimized assays, developed from curated libraries of tens of thousands of fluorogenic peptide sensor substrates, and also provides services to develop novel optimized assays for you. Why not use the best substrate for your assays, designed for your enzyme?
  • We will either transfer the new assay methods to you to use in your own laboratory or can provide screening, potency or profiling services, saving you time, money, and resources. Our highly skilled scientists bring years of experience with kinases and phosphatases to bear to solve your problems. Our goal is to help you get as quickly as possible, to the best candidate molecules, with the highest efficacy.
