A rapid method for PCR amplification of DNA directly from cells fixed in Carnoy's fixative.


We describe a method for rapid and efficient polymerase chain reaction (PCR) amplification of specific target DNA sequences directly from cells fixed in 3:1 methanol-acetic acid (Carnoy's fixative) for routine cytogenetic analysis. The fixed cells used had been stored at -20 degrees C from a few weeks up to 6 years. Primer sets used correspond to loci on an… (More)
