Figure 1. T. cruzi whole cell binding aptamer sequences.

Figure 1

Nucleotide sequence including the conserved T7 and SP6 primer binding sites, depicted in lower case letters, of the four selected RNA aptamers, Apt16, Apt25, Apt68 and Apt79, obtained from the T. cruzi trypomastigote whole-cell SELEX is represented (A). The length of each aptamer sequence is indicated on the right. Predicted secondary structure obtained from Minimal Free Energy (MFE) calculations of Apt16, 25, 68 and 79 are shown in panels B, C, D and E, respectively.
