i use Xylene Cyanol Blue in my PCR reaction for loading
my gel just after the PCR and i add in the reaction
sucrose
During my test i saw that the sucrose reduce the non
specifics bands perhaps because sucrose is a very large
molecule
i used it a 2 4 or 6% sucrose in final reaction
i hope that you understand what i mean because i know
i have a very bad english...sorry !
