Abstract: The present invention relates to methods for identifying improved stereodefined phosphorothioate oligonucleotide variants of antisense oligonucleotides utilising sub-libraries of partially stereodefined oligonucleotides. The methods allow for the efficient identification of stereodefined variants with improved properties, such as enhanced in vitro or in vivo activity, enhanced efficacy, enhanced specific activity, reduced toxicity, altered biodistribution, enhanced cellular or tissue uptake, and/or enhanced target specificity (reduced off-target effects).
