384-well microplate for use in time-resolved fluorescence, luminescence, Alpha, and radiometric assays. This black polystyrene CulturPlate™ is sterile and tissue-culture (TC) treated for cell-based assays. Tissue-culture treated microplates are supplied with lids.The CulturPlate is PerkinElmer's microplate designed for cellular assays, tissue-culture treated and sterilized by gamma-irradiation to facilitate adherent cell growth. The optimized well design and high quality plastics provides low background and crosstalk. CulturPlates are uniquely engineered to be the same height for 96-, 384-, and 1536-well plates, and with extraordinary well flatness for ease in automation. Leveraging years of assay and instrument experience in plate detection, PerkinElmer designs better Microplates for better performance that guarantees better results for all PerkinElmer applications..
