Methods and apparatus for sequential amplification reactions

The invention provides methods and apparatus for carrying out multiple amplification reactions in a single reaction chamber by successive cycles of loading reaction mixture, amplifying, and removing spent reaction mixture in a fluidly closed reaction system. In particular, the present invention allows amplification of a plurality of target polynucleotides from a single sample by carrying out under closed-loop control successive amplifications of different target polynucleotides from different portions of the sample.. ...

Integrated purification and measurement of dna methylation and co-measurement of mutations and/or mrna expression levels in an automated reaction cartridge

In various embodiments methods of determining methylation of dna are provided. In one illustrative, but non-limiting embodiment the method comprises i) contacting a biological sample comprising a nucleic acid to a first matrix material comprising a first column or filter where said matrix material binds and/or filters nucleic acids in said sample and thereby purifies the dna; ii) eluting the bound dna from the first matrix material and denaturing the dna to produce eluted denatured dna; iii) heating the eluted dna in the presence of bisulfite ions to produce a deaminated nucleic acid; iv) contacting said deaminated nucleic acid to a second matrix material comprising a second column to bind said deaminated nucleic acid to said second matrix material; v) desulfonating the bound deaminated nucleic acid and/or simultaneously eluting and desulfonating the nucleic acid by contacting the deaminated nucleic acid with an alkaline solution to produce a bisulfite converted nucleic acid; vi) eluting said bisulfite converted nucleic acid from said second matrix material; and vii) performing methylation specific pcr and/or nucleic acid sequencing, and/or high resolution melting analysis (hrm) on said bisulfite-converted nucleic acid to determine the methylation of said nucleic acid, wherein at least steps iv) through vi) are performed in a single reaction cartridge.. ...
