Phosphorylation Site Specific Aptamers for Cancer Biomarker Peptide Enrichment and Detection in Mass Spectrometry Based Proteomics
21 January 2015

The development of renewable capture reagents that could be produced more efficiently and cost-effectively than monoclonal antibodies is a key topic in diagnostics and therapeutics. This application note shows the development of high-affinity aptamers against specific phosphorylated and unmodified peptide target sequences of certain cancer biomarkers of interest, utilizing a patented, multiplexed “Systematic Evolution of Ligands by Exponential enrichment” (SELEX) approach.
