METHOD FOR AMPLIFYING ALL DNA FRAGMENTS IN A SAMPLE
The invention concerns a method for characterising all the DNA fragments in a sample, said fragments being small in size and often damaged and/or in the form of traces in particular in finished or transformed products. The invention is characterised in that it comprises a preliminary amplification step of all the DNA fragments before an optional specific amplification, which makes the method highly suitable for analysis, by molecular hybridisation, in particular on DNA chips, of all the DNA derived from any type of sample possibly of high complexity and/or having being subjected to denaturing treatment.
