Characterization of BBa_K542009
pLacI Regulated AG43
Aim
To verify Assembly Standard 10 complianceMethod
Escherichia coli bacterial culture containing plasmids BBa_K542009 (coding region of Ag43 only), was inoculated overnight in LB-chloramphenicol medium in a shaking water bath at 370C. Plasmid mini preps were conducted with a Qiagen plasmid mini prep kit. Single and double restriction digests were carried out accordingly:Restriction digests with EcoRI, XbaI, SpeI and PstI was performed to linearize the vector and to confirm the existence of unique restriction sites, as required by the iGEM biobrick Assembly standard 10 rules. Double restriction digests with EcoRI plus PstI and XbaI plus SpeI were performed to separate the BBa_K542009 insert from the pSB1C3 plasmid backbone. Digests were incubated at 370C for 2 hours and analysed by gel electrophoresis. Theoretical maps were used to calculate the expected sizes of the fragments and to compare them against the gel electrophoresis results.
Results
Fig.1 Gel electrophoresis on standard restriction digests of BBa_K542009
Restriction digests were separated on a 0.8% agarose gel. Lane 1; NEB 1 kb size standards ladder, Lane 2; uncut plasmid, Lanes 3-6; plasmid cut with either EcoRI, XbaI, SpeI or PstI respectively, Lane 7; plasmid cut with EcoRI+PstI, Lane 8; plasmid cut with XbaI+SpeI.
