A simple technique for harvesting lymphocytes cultured in Terasaki plates.
A simple method has been developed for harvesting lymphocytes from Terasaki microplates based on a culture technique where the plates are inverted and the cells grown on the hanging meniscus of the medium in each well. Sixty individual filter discs were prepared in wells in a polycarbonate harvesting plate. A dry Terasaki plate was used to cut these filters with the harvester acting as a die. The inverted culture plate was then lowered onto the harvester to allow the cells on the meniscus from each well to be absorbed on the appropriate filter disc. The culture plate was then discarded and the cells on the filters washed in the harvester. The wash solutions were removed by suction through holes below each filter. The time taken to harvest the cultures from 60 wells of a plate was 3--5 min.
