It are designed for advanced immunological assays and laboratory applications. Made from high-quality polystyrene (PS) for strength and optical clarity, these microplates feature a black exterior with a transparent bottom to allow precise sample observation and analysis. The F-bottom design ensures superior sample recovery and efficient mixing. The high-binding immunological surface is optimized for immobilization of IgG and provides the highest binding capacity for molecules with mixed hydrophilic and hydrophobic regions, ideal for standard ELISA assays.
