ABSTRACT:
SUMMARY OF THE INVENTION
The present invention includes methods and apparatus for the automated generation of nucleic acid ligands against virtually any target molecule. This process is termed the automated SELEX process. In its most basic embodiment, the method uses a robotic manipulator to move reagents to one or more work stations on a work surface where the individual steps of the SELEX process are performed. The individual steps include: 1) contacting the candidate nucleic acid ligands with the target molecule(s) of interest immobilized on a solid support; 2) partitioning the nucleic acid ligands that have interacted in the desired way with the target molecule on the solid support away from those nucleic acids that have failed to do so; and 3) amplifying the nucleic acid ligands that have interacted with the target molecule. Steps 1-are performed for the desired number of cycles by the automated SELEX process and apparatus; the resulting nucleic acid ligands are then isolated and purified.
