GTPγS assay is an integral part of the MULTISCREEN GPCR assay platform, utilizing high-quality HTS-ready membrane and cell lines to provide answers to questions.

MULTISCREEN Receptor Internalization Assay permits high throughput screening of GPCR receptor activity, independent of downstream signaling. It allows screening regardless of ligand or key signaling modalities maybe unknown. It also provides insights into receptor pharmacology to help triage drug lead candidates.

Multispan brings its expertise in cell-based assay development to the functional analysis and validation of targets for precision medicine. We discuss applications in rare disease and pharmacogenomics of key target classes

In this paper, we discuss the characteristics of GPCRs that make it so difficult to develop effective anti-GPCR antibodies. We then discuss Multispan’s customized MULTISCREEN GPCR FACS binding and functional assays for antibody profiling.

Multispan’s panel of GPCR orthologs can enable critical assessment of species-specific variations in target binding activity and modulation of GPCR signaling that could impact in vivo efficacy in small and large animal models.

GPCRs have historically been among the most important classes of pharmaceutical targets across a wide range of clinical indications. Recent clinical, scientific and technical advances have also opened new therapeutic avenues to exploit members of this class. In this paper, we discuss how Multispan’s MULTISCREEN GPCR panel can provide important insights during the development of new compounds and in repurposing existing therapies.

Every year, researchers invest billions of dollars toward clinical approval of innovative new drug compounds. However, the U.S. Federal Drug Administration (FDA) only accepts a select number of new chemical entries every year. In fact, from 2011 to 2018, the FDA only approved 309 new drugs. While this is a marked improvement from the approval rate of decades prior, it still points to the administration’s selectivity. One way to streamline the drug development process? Invest in assay development. This analytical function is key to high-quality drug discovery research. Today, we’re diving into the important role it plays. Ready to learn more? Let’s dive in!

An allosteric modulator binds to an allosteric site on a protein, such as a receptor or enzyme, distinct from the active site, which alters the activity of the protein. This modulation of enzyme and receptor function differs from that of traditional agonists and antagonists. A positive allosteric modulator will enhance the affinity and/or efficacy of a receptor for its endogenous ligand or agonist, and increase the catalytic activity for enzymes. A negative allosteric modulator will reduce the affinity and/or efficacy of the receptor, and decrease the catalytic activity for enzymes.
