The assay chip 2 as described in the polymer chip section can be ordered with integrated arrays. microfluidic ChipShop will spot the desired molecules (e.g. DNA probes, antibodies, antigens etc.) on the polymer surface and will cover the chip with the thin cover foil. Reagents like antibodies or antigens and reference material have to be provided by the customer or will be charged separately. For the order of a special array a process set-up needs to be ordered in advance.
