Southern blot question:
Does anybody know how much better a genomic fragment will work as a
probe then a cDNA piece?
In other words: how important is continuity in hybridization?
Obviously, if we have a cDNA probe of 500bp it should hybridase
stronger with a one-exon gene then with a hundred-exons gene.
What would be a reasonable UNINTERRUPTED hybridization length over
which it shouldn't matter any more?
A lie isn't a lie if it is in reply to a question
that the questioner has no right to ask.
