When I electrophorese my pcr products, I am looking for a band around 200 bases long (pretty small). The problem is that the band usually comes out right at the dye front, which makes UV visualization a slight problem. Is there another dye I can use that will run a bit faster or slower than bromphenol blue? I could try just using glycerol and edta in my loading buffer, leaving out the dye. All suggestions welcome... Daniel G.
