Preparation of CIM® Methacrylate Monolithic 96 – Microtiter Plate Format

Analysis of a large numbers of samples requires chromatographic supports that not only enable fast separation and purification of a target biomolecules from a complex matrix but are also involved in an automation process. The 96 – microtiter plate format enables both. Although they are routinely used for decade's only recently few reports about the microtiter plates bearing monoliths as a separation media, were reported [1]. Because of advantageous properties such as flow unaffected dynamic binding capacity and resolution 96 - microtiter plates with methacrylate based monolith were prepared. Characterisation of such plate demonstrated that uniform flow rate can be achieved through all wells and no leakage is present. Efficient separation of proteins was achieved within minute. Furthermore CLC (Conjoined Liquid Chromatography) concept [2] originally derived for analytical columns on CIM disk, can easily be extrapolated to microtiter plates. We demonstrated that multidimensional chromatography with 96 – well plate is feasible and can further accelerate screening processes.
