Webelectrophoresis, post-staining of gels is highly recommended. Post-staining with GelRed® results in superior sensitivity and eliminates the possibility of dye interference with DNA migration. Agarose gels can be precast with GelRed®, however, GelRed® may affect the migration or resolution of some DNA samples in precast gels. WebGelRed affects the running of the DNA since it binds to the DNA. Since it affects all DNA molecules in the same way, it doesn't matter. Undefined bands usually come from the PCR reaction itself,...
