Figure 3From: A novel surface protein of Trichomonas vaginalis is regulated independently by low iron and contact with vaginal epithelial cellsSouthern blot analysis of T. vaginalis genomic DNA. Ten micrograms of genomic DNA was digested with restriction enzymes before separating on 0.9% agarose gels and blotting onto Hybondâ„¢ -N+ membranes. The membranes were then probed with a labeled PCR product containing the coding region of the tv44 gene. Numbers on the left show the positions of a 1-kilobase (kb) ladder.Back to article page
