Fig. 3From: Predominance and association risk of Blastocystis hominis subtype I in colorectal cancer: a case control studyRepresentative 1% agarose gel showing Blastocystis subtyping based on PCR-STS analysis. (Lane L) shows 100Â bp DNA ladder; (Lane 1) represents negative control. (Lanes 2,5,8 and 12) show 704Â bp PCR products and represent Blastocystis subtype-V. (Lanes 3,4,7,11 and 13) show 351Â bp PCR products and represent Blastocystis subtype-I. (Lanes 6,9 and 10) show 650Â bp PCR products and represent Blastocystis subtype-IIBack to article page
