A rapid and easy method for the DNA extraction from Cryptococcus neoformans

DNA isolation from C. neoformans is difficult due to a thick and resistant capsule. We have optimized a new and rapid DNA isolation method for Cryptococcus using a short urea treatment followed by a rapid method using a chelex resin suspension. This procedure is simpler than previously reported methods. DNA isolation from C. neoformans is difficult due to a thick and resistant capsule.
