Recently, I clone a insert(about 2.5k) by T/A cloning and I would like
to cut the insert from the T/A vector. I inoculate the cell from the
glycerol stock and grow in LB-AMP broth with shaking overnight. After
miniprep and restriction digestion, I only obtain a small smear on the
gel. Therefore, , I should retransform the plasmid every time. I don.t
know what is the problem. Please give me any suggestion.
Thanks a lot!
