Rusconi Mix (That's what we call it, maybe you can find a reference when
500ul Lysozyme (10mg/ml)
500ul 0.5M EDTA
250ul 1M Tris pH 7.5
100ul RNase (10mg/ml)
1.15ml Glycerol (87%)
0.02%Bromophenol blue (endconc. of 2mg/10ml)
store at -20 in aliquots
suspend 1 colony in 12-15ul
let stand at RT 10-15 min
add 2ul Phenol, vortex, spin 2'
Load aqueous supernatant on gel - plasmids with insert will run slower
so you can see it, I hope your insert is big enough...
