الوصف: | A method of thermal dissociation of DNA–protein conjugates was developed for the selection of aptamers to human alpha-fetoprotein. The method is based on the identification of the DNA oligonucleotides from the combinatorial DNA libraries with the highest specificity to targets, which remained within the conjugate after two stages: a) washing of unbound sequences; and b) removal of the sequences bound to the DNA but displaying a low affinity to it. The undestroyed most stable complexes were subjected to the thermal dissociation with the involvement of the corresponding oligonucleotides in the next rounds of selection. A comparison of the proposed method with the standard washing demonstrated a more intensive enrichment of the library. Due to the tighter conditions for washing of the target-bound DNA oligonucleotides the use of thermal dissociation can increase the efficiency of selection of highly specific aptamers to their molecular targets. |
