Dependence of click-SELEX performance on the nature and average number of modified nucleotides.

ABSTRACT: The click-SELEX procedure enables the identification of nucleobase-modified aptamers in which chemical entities are introduced by a copper(i)-catalysed alkyne-azide 'click' reaction. Here we report on the impact of modified nucleobases on PCR conditions and the average amount of modified nucleobases on click-SELEX performance. We demonstrate click-SELEX being strongly dependent on which and on how many modifications are used. However, when using C3-GFP the number of modifications did not impact the overall success of the selection procedure.
