IMPROVEMENTS IN OR RELATING TO ELECTROPHORESIS

摘要

Apparatus for simultaneously supplying a plurality of samples to an electrophoretic gel comprises an array of a plurality of tubes, each tube having an inlet end for receiving a sample from a receptacle and an outlet end for supplying a sample to a well in an electrophoretic gel; and a multichannel pump through which the array of tubes passes for simultaneously pumping samples through individual tubes in the array from respective sample receptacles to respective wells of the gel. The invention also provides a method of simultaneously supplying a plurality of samples to a plurality of wells in an electrophoretic gel from a plurality of sample receptacles, comprising simultaneously pumping samples through a plurality of tubes in an array, each tube leading from a respective sample receptacle to a respective well. The invention finds particular, but not exclusive, application in connection with sequencing of DNA, where large numbers of samples require electrophoretic treatment.
