Examination of aliquots of supernatants from <i>S</i>. <i>haematobium</i>-positive patients´ urine samples by LAMP.

<p>Figure shows the LAMP results (up, by color change; down, by agarose electrophoresis) when using aliquots of 100 μL of supernatants to obtain DNA as template by using (A) the i-genomic Urine DNA Extraction Mini Kit (Intron Biotechnology, UK); (B) the heating NaOH-SDS method and (C) the rapid heating method. Lanes M: 50 bp DNA ladder (Molecular weight marker XIII, Roche); lanes Sh: genomic DNA from <i>S</i>. <i>haematobium</i> (1 ng); lanes 1–18: <i>S</i>. <i>haematobium</i>-positive samples; lanes N: negative controls (no DNA template).
