BUFFERS FOR NON-CONTACT MICROARRAY SPOTTING

摘要

The present invention relates to a method of microarray spotting which utilises improved buffers. In particular it relates to buffers being used in a non-contact microarray system and toamethod of printing samples wherein samples are prepared in a sample buffer, nozzles are then purged in a forwards direction with a system buffer; samples are then aspirated into the nozzles displacing at least a portion of a system buffer without mixing with it; and samples are then printed through the nozzles.
