In vitro assay design and development to accelerate projects at every stage of drug discovery and development.

RxBioscience In Vitro

Our experienced team of scientists are experts in in vitro assay design and development. We work closely with other teams at RxCelerate throughout all phases of the drug discovery pipeline, striving to deliver bespoke and cost-effective experimental solutions with data-rich endpoints.

We approach complex questions from first principles, striving for scientific excellence with each project. Our projects begin with a detailed proposal created following extensive review of scientific literature. Experimental programmes are carefully planned to maximise endpoints and optimise cost and time effectiveness. Close contact with the client is maintained throughout and key data is shared in real time to allow a flexible approach in response to experimental outcomes.
