Hi Kelvin

depends on the organism, but if it's E. coli:

- use toothpick to touch colony, shake a few times in 50 ul aqua dest. Put
the toothpick in Luria broth to grow the colony in case it's positive and
grow overnight.
- Boil water+bacteria for 5 min
- cool on ice
- spin 5 min at full speed in microcentrifuge to pellet insoluble matter
- take 1 or 2 ul of supernatant for PCR

hope this helps
