Gifford Bioscience Limited is a preclinical contract research organization (CRO) providing specialist services in radioligand binding assays, receptor occupancy studies, autoradiography and SPR.
At Gifford Bioscience, we employ “gold standard” radiometric methods, for maximum sensitivity and robustness, together with label-free, kinetic affinity techniques. We use cell membranes, live cells, human tissue and animal tissue.
Determination of receptor affinities and binding parameters for test compounds in a tissue homogenate or cell preparation.
Measurement of the degree to which a test compound engages its target receptor in live cells, tissues or in an animal.
Measurement of a compounds transport into cells or efflux from cells. Determination of a compound’s potency and efficacy.
Kinetic, label-fee measurement of a drug’s affinity for its receptor using Surface Plasmon Resonance (SPR).
Small Molecules, Binding to AT2 Site on ACE2, Unlikely to Prevent COVID-19 Spike Protein Binding
Angiotensin II and SARS-CoV-2 ‘spike’ protein bind to independent sites on angiotensin converting enzyme 2. We used the Biacore Surface Plasmon...
COVID-19 Decoy: ACE2 in Solution “Decoys” Spike Protein, Inhibiting Binding to Surface Bound ACE2
Using the Biacore Surface Plasmon Resonance (SPR) technique, we have quantified the kinetic receptor binding parameters for COVID-19 / SARS-CoV-2...
