384-well assay plates from Porvair Sciences are available in black, white and clear. These have been optimised for fluorescence, luminescence/scintillation and ELISA/turbidity measurements respectively. There are two working volumes: 30μl/well or 120μl/well. All 384-well assay plates are available in standard, high bind and tissue culture treated formats. The low volume 384-well assay plate is designed for high throughput screening with 30μl total volume to reduce the mount of sample and reagent required for the assay.
