Enrichment was analysed by comparing the signals from the unselected mock library (R0) with the outputs of the first (R1) and second (R2) round of selection using an antigen specific phage capture ELISA (Fig. 6).
After 10 rounds of selection and amplification, selected aptamers have been characterised using a number of techniques, including fluorescence quenching, ELISA and competition ELISA procedures and a FRET type assay.
After 8 rounds of selection with chlorpyrifos, a selected population developed a 191.0-fold 191.0-fold comparesistance compared
Through 13 rounds of selection, the CS-SELEX generated high-affinity ssDNA aptamers, and the selected ssDNA aptamer ZE2 demonstrated the highest specificity and affinity to E2-positive cells.
After 10 rounds of selection, high-throughput sequencing was used to identify enriched aptamer candidates.
After 11 rounds of selection, the enzyme was nearly 10,000 times more efficient.
In total, 4 rounds of selection were taken.
Consequently, the fraction of functional SH3 sequences capable of binding to the VSL12 peptide increased in the SH3 RNN 28 library after 3 rounds of selection (Fig. 4), but not in the SH3 YNN 28 library after even 5 rounds of selection (Fig. S1).
Unmutagenized parasites were all nonviable after 2 rounds of selection, while rare individuals within the mutagenized populations were able to grow and lyse host cells successfully at concentrations up to 5 µM 4-BPB after 13 rounds of selection.
