acrylamide gels and DNA markers

[Dr. Kimberly Walker]

Hi 
Thanks for all the responses I got on Primer Extension!
I think it is going well, for example, I get globs of discrete size on my 
acrylamide gels and some of them are radioactive.

My question is, is there some strange function of prestained BRL markers 
that refuses to let them enter the acrylamide gels?  I know that the 
600bp fragment of 100 bp size standards is supposed to run anomolously, 
but do all markers (Lambda HindII, Lambda BstEII, PhiX 174 HaeIII) run 
strangely on acrylamide gels?

Just a thought.
