Bacterial DNA extraction protocol

Electroporation
Electro-competent cells of E. coli DH5α are electroporated at 1.25 mV, immediately we add SOC medium to the bacteria and we incubated on a shaker at 37°C for one hour, then, we culture cells in a solid medium containing the antibiotic of selection.

If needed add 1 μL of DMSO per reaction, and adjust the amount of H2O to a final volume of 10μL.
PCR - Colony
Based on the protocol used with Taq polimerase, add 1μL more of H2O and take a few cells from the strain pricking it with a toothpick and mixing them with the other PCR reactives instead of using purified DNA.
