	We are trying LA (long and accurate) PCR of genomic DNA.  We have been 
successful at some genomic loci and not others.  What should we try on loci
that are difficult?  We are using accurate primers that should amplify the
region of interest. 
	Also we have noticed possible amplification product when run on a 
low percentage agarose gel (0.4%); however, this product will not migrate 
out of the wells.  We have tried various methods (i.e. SDS, 
heating, etc.) to resolve this problem to no avail!!
	Any ideas would be greatly appreciated.
