Genomic DNA Prep PMID 10591650, Restriction digest of 500 ng of genomic DNA with MboI, Ligation of cut ends at 5 ng/μl concentration (Hutchison99), Transposon detection PCR reaction 10 μl test volume, Inverse PCR for transposon location identification, Inverse PCR for sequencing transposon location, https://openwetware.org/mediawiki/index.php?title=Mesoplasma_florum:Inverse_PCR_Transposon_location&oldid=288233, Hutchison used DraI as a cutter, but this is a blunt cutter, making religation difficult, MboI cuts at GATC sites, and is insensitive to 5-me dCTP methylation (sensitive to methylation of A), MboI cutting frequency calculation: p(cut) = (.13)(.37)(.37)(.13) = .00231, Expected fragment length = 1/ .00231 = 432 bp + length from primer site to end of transposon, Expected PCR fragment length is twice this length, or about 1Kbp, Genomic DNA from single colony transposon insertion event, Cycle 5 minutes at 95° initial denturation, Sequence with both M13forward(-47) primer and T7 universal primer, locate the MboI cut site (GATC) in the sequencing results, locate the end of the transposon sequence (ME end, reverse complemented here, agatgtgtataagagacag), Identify the duplicated 9bp insertion site surrounding the insertion event, Locate the sequence from the ME end to the GATC cut site on the, The sequence from the M13F(-47) and T7 Universal primers should be adjacent, and oriented in opposite directions on the genome.
