250 bp-DNA-Ladder, DNA-ladder (lyophil.) + gel loading, 50 µg, plastic250 bp DNA Ladder, DNA ladder (lyophil.) + gel loading, buffer, not pre dyed, Density (D) 1 g cm, Storage temp. 20 C Universal ladder for size analysis of plasmids and DNA insertions. Two fragments of 1500 and 2500 bp have been reinforced for easy orientation in the gel. The DNA amount per band has been optimised in such a way that a small running distance and low amounts of marker are sufficient for optimum separation. Fig.: 1,8 % agarose (NEEO, Art.
