摘要

During recent years there has been a growing trend towards more frequent use of cell-based assays for drug discovery. Cell-based assays differ from more traditional screening enzyme- or antibody-based assays in that they enable the analysis of whole cell responses to compounds of interest, providing a better model for tests such as toxicity prediction. The use of live cells requires special consideration, and technological advances in the field are leading to products that are simple to use while remaining accurate and sensitive. rnTrevigen has introduced the CultreCoat~⊕ Cell Adhesion Assays for assessing factors that influence cell-matrix interactions. The product comes in a simple, standardised, high-throughput adhesion assay format, offering 96-well plates coated with Basement Membrane Extract, Laminin I, Collagen I, Collagen IV, Fibronectin, Vitronectin, or an array of all six ECM proteins. A black stripwell format minimises background, providing increased sensitivity. Calcein labelling allows direct comparison between the number of cells loaded and the number of cells that adhere, and additional controls are provided for determining background and non-specific binding.
