Background: Most molecular biology research findings require markers such as DNA ladders to detect and quantify nucleic acid fragments length by electrophoresis in routine task. Methods: In this study, we report a method to prepare a 100 pair base DNA ladder based on PCR technique. The bacterial plasmid pMAL-C2X was used as the template DNA in PCR. PCR products were extracted by phenol/chloroform, precipitated with ethanol and mixed proportionally. Results: Finally, a set of 7 primers (5 revers and 2 forward) successfully designed. The amplified PCR fragments were quantified by nanodrop and the bands size were estimated by gel electrophoresis along with a co-migrating commercial 100 bp ladder in 1.5% agarose gel. The results indicated that the clear and sharp bands of 100 bp-1000 bp were successfully generated by o.. View more»
