I believe that it provides a quality and reproducibility that is difficult to match with horizontal apparatus. We use gel boxes made be Watson Products, PO Box 247, (818) 797-5773. They are a "mom & pop" company that started making vertical gel apparatus just as agarose was being developed for DNA fractionation. They sell frosted (sand-blasted) plates, which are essential for holding low-percentage gels in position. Bill Pearson
