A comparison of DGGE profiles of PCR amplified bacterial 16S rRNA gene. DNA was extracted using FastDNA® SPIN Kit for Soil (FSo) using 25 mg of fecal specimens collected from four human subjects (Subject A, B, C, and D; n = 4 for each subject). Bacterial fingerprint profile is based on 35 to 60% DGGE gel gradient. Lane 1 to 4 show bacterial fingerprint profile of consecutive fecal samples collected from each subject.
