Hi everyone,
I need some help on the identification of unexpected bands.
Extraction of plasmidic DNA from pBluescriptII (lane 1,6) and extraction of genomic DNA from Lactobacillus plantarum (lane 4,5).
pBluescriptII ( ~ 3kb) and Lactobacillus ( ~3300 kb)
Regarding plasmidic DNA (lane 1,6) there are two bands. First band could correspond to the supercoiled and the band below could correspond to the circular, single stranded ?
Regarding genomic DNA, there are 2 bands between 1500bp and1000bp that I can´t understand why they appear. Don´t know if working with Lactobacillus is normal to see these 2 bands.
Thanks
