Figure 4From: Real-time quantification of wild-type contaminants in glyphosate tolerant soybeanEnd-point PCR detection of the 506 bp wt-specific sequence at the RR locus. (A) Lanes 1–30: conventional soybean varieties. (B) Lanes 1–20: RR soybean varieties homozygous for the transgene. ntc = non target control. mw = molecular weight marker 100 bp ladder.Back to article page
