Comments: In order to increase the efficiency of subcloning with the Series-11 Macrobac plasmids we developed a new strategy the uses LIC (Ligation Independent Cloning). The problem with the Series-11 ligation mediated subcloning was that when the plasmid size approached or exceeded 20 kb we had to screen many colonies to find a positive. We developed a strategy to use LIC for subcloning. Because this method uses no ligase, the cloning background associated with re-ligation of the empty plasmid are eliminated. 438-B has a TEV cleavable His6 at the N-terminus. The 438-B vector use the LICv1 Forward and Reverse primers. LICv1Forward - 5'-TACTTCCAATCCAATGCA-3' LICv1 Reverse - 5'-TTATCCACTTCCAATGTTATTA-3' As the target plasmid size gets >20kb you may have to increase the amount of DNA you anneal and/or transform. We have found this method gives no background colonies at all and 100% of the colonies we pick are positive. The cells we transform into are XL1Blues with a competency ~6x10^7cfu/ul.
