Multi-well Plates

96 well plates These are plates made of polystyrene having 96 wells arranged in a rectangular matrix which can be used as small tubes for various biological, forensic and pharmacological purposes and experiments. They are widely used for ELISA (Enzyme-linked Immunosorbent assay), some versions of the plate have hydrophilic surface making them more suitable for cells to adhere and are therefore used in tissue culture and bacteriological experiments. Each well can store volumes of liquid ranging from Nano-liters to several milliliters. The wells are separated via gaps. These wells can also be used as a rack to support tubes especially in the case of PCR, qPCR and other DNA template amplification protocols. These plates are available in various dimensions Types and design • The bottom and surface of these plates are flat • The bottom may have distinct shapes like ‘U’, ‘C’, and ‘V’ • Bottom may be transparent or black/white pigmented • Transparent bottoms are useful for fluorescent and immunofluorescent assays • Titanium dioxide may be added into polystyrene to increase optical absorbance • Plates have labeled rows and columns
