here is a one tube mini-prep method, also referred to as: the fast
boiling method.

- grow your E.coli in LB or TB with antibiotics
- spin your cells for 15 secs in eppi
- discard the supernatant and
- suspend your cells in 350 ul STET
           10 ml Triton X100
           20 ml EDTA 0.5 M
           10 ml Tris pH 8.0 1.0 M
           16 g Sucrose
           add water to 200 ml

- you can now add lysozyme (2 ul 10 mg/ml)
   but it is not really necessary for most E. coli
- 60 secs 100 degrees (really 100, BOILING waterbath)
- spin it down (say 20 min in eppendorf or 10 min in SA600 rotor 40,000
- take the pellet out with a toothpick and throw it away, leave the
supernatant in the eppi
- add 350 ul isopropanol to the supernatant, mix it well
- 15 min in eppendorf centrifuge, full power
- discard the supernatant, dry the pellet
- solve the pellet in 100 ul TE
- use 10 for digest
