(A) HPLC chromatograms of precursor amine-modified ssDNA (left) and crude succinimidyl-modified ssDNA (right) after reaction with DSS. (B) Reducing SDS-PAGE gel analysis of three commercial antibodies before and after reaction with succinimidyl-ssDNA. Protein bands were visualized by Sybr-gold staining, revealing ssDNA-modification predominantly on heavy chains. (C) Native PAGE gel analysis of commercial antibodies before and after reaction with succinimidyl- modified ssDNA reveals high labeling efficiency to mono-, di, and tri-oligonucleotide conjugates for all three antibodies.
