Uniquely engineered light gray AlphaPlate™ microplates combine the best features of white microplates (excellent signal-to-background) and black microplates (decreased well-to-well crosstalk) for superior assay window and sensitivity in comparison to any other plate for luminescence assays. AlphaPlates are compatible with a variety of technologies for luminescence-based assays but are specifically designed for use with AlphaLISA® and AlphaScreen® technologies.
