PCR primers

Tue Apr 8 19:47:02 EST 1997

Would not the best way of ensuring or controlling for amplification from genomic 
DNA be to use primers to the introns?  Or perhaps PCR across a small intron so you 
can see a difference in size in the PCR fragments of cDNA and genomic.

Best wishes, Martin Slade
