Abstract
Animal cell colonies are picked up automatically by an apparatus having a picking head with a plurality of hollow pins and an integrated imager for capturing an image of adherent or non-adherent animal cell colonies held in liquid or semi-solid medium. Image processing identifies the locations of the animal cell colonies to be picked. Picking an animal cell colony is performed by aligning each of the hollow pins in turn with a target animal cell colony location, introducing the hollow pin into the medium, and aspirating the animal cell colony into the hollow pin. In the case of an adherent colony, the distal end of the pin is forced into oscillation to detach the animal cell colony prior to aspiration. The animal cell colony is dispensed into a well plate by increasing pressure in the fluid conduit.
