This Corning 384-well solid black polystyrene microplate has flat-bottom square shaped wells with a well volume of 112µL and a recommended working volume of 20 to 80µL. It is ideal for todays more sensitive assays and plate readers. Black wall plate has reduced autofluorescence, higher signal to background ratio and lower CVs. Not treated (or medium binding) polystyrene surface is hydrophobic in nature and binds biomolecules through passive interactions. The microplate is suitable primarily for the immobilization of large molecules, such as antibodies, that have large hydrophobic regions that can interact with the surface. The untreated microplate has a binding capacity of approximately 100 to 200ng IgG/sq cm. It conforms to standard microplate footprint and dimensions. Enhanced flatness provides low intra- and inter-plate CVs. This is the suggested replacement for Corning Item Numbers 3708 and 3710. Non-Sterile. Lid Not Included. Material: Polystyrene.
