Reaction system for performing in the amplification of nucleic acids
First Claim
1. A disposable unit comprising a thermally conducting layer and a facing layer separated by a spacing layer having multiple reagent wells defined therein, the reagent wells having well openings through which sample is introduced, and wherein the well openings of the reagent wells and one or both of the thermally conducting layer and the facing layer of the unit are configured such that once the reagent wells are filled with sample, the well openings of the reagent wells are sealable by mechanically deforming one or both of the thermally conducting layer and the facing layer of the unit, without heat-sealing.

Abstract
A method of carrying out an amplification reaction, said method comprising supplying to a well in a disposable unit (a) a sample which contains or is suspected of containing a target nucleic acid sequence (b) primers, nucleotides and enzymes required to effect said amplification reaction and (c) a buffer system, and subjecting the unit to thermal cycling conditions such that any target nucleic acid present within the sample is amplified; wherein the disposable unit comprises a thermally conducting layer and a facing layer having one or more reagent wells of up to 1000 microns in depth defined therebetween; and the reaction mixture comprises at least one of the following: A) a buffer system wherein the pH is above 8.3; B) a detergent; and/or C) a blocking agent. Apparatus for effecting the method as well as disposable units for use in the method are described. The method is particularly suitable for rapid PCR reactions.
