To illustrate the effect of varying the amount of DNA loaded in a lane, we did some initial testing at three different size cuts, 3kb, 5kb and 8kb with four different DNA inputs: 1µg, 3µg, 6µg and 10µg. A stock of 1 µg/µL of E.coli genomic DNA from Sigma (Type VIII), digested with Dra I, was used as ...
