Transferable Solid Phase (TSP) is similar to a 96-well plate lid with 96 attached pins. When lid is placed over the well plate, the pins are immersed in the wells. Used for replating and screening of 96-well plates containing transformants or library clones, screening hybridoma cultures or expression libraries, adsorption of mixed proteins or antibodies directly from cultures. When pre-coated with antigen or antibodies, a specific analyte from cultures may be assayed via efficient transfer from one plate to another. Can be assayed in the Nunc MicroWell® 96-well plates. Sterilized, polystyrene.
