Screening of DNA aptamers inhibiting Taq DNA polymerase using algorithm mimicking evolution.


We have developed a novel method for screening DNA aptamers by an algorithm mimicking evolution, which have enabled selection by not affinity but inhibitory activity of aptamers. Using this method, we have successfully obtained DNA aptamers that inhibit Taq DNA polymerase in a few hundred-nanomolar range. This result shows this method would be useful for screening aptamers as an enzyme inhibitor.

Using Polbase tables:


Tables may be sorted by clicking on any of the column titles. A second click reverses the sort order. <Ctrl> + click on the column titles to sort by more than one column (e.g. family then name).


It is also possible to filter the table by typing into the search box above the table. This will instantly hide lines from the table that do not contain your search text.
