These 384-well plates have been optimized for fluorescence, luminescence/scintillation and ELISA/turbidity measurements respectively. There are two working volumes: 30uL/well or 120uL/well. All 384-well assay plates are available in standard, high protein bind and tissue culture treated formats. The 384-well format, with its higher density of wells, allows more work to be carried out in a standard sized plate, resulting in higher throughput. Well volume is 120uL per well. All of these plates are manufactured from high quality polystyrene.
