X-Aptamers are the next step in the evolution of aptamer technology. They are synthetic affinity reagents that incorporate natural as well as chemically-modified DNA or RNA nucleotides.

Sandwich Ab:XA Pair

Do you have an antibody and wish that you could find a partner for it that binds your target concurrently? Having a sandwich pair of affinity molecules that bind simultaneously to a target provides numerous advantages.

Selection Process

AM Biotech uses a proprietary bead-based technology to select X-Aptamers. The single round, bead-based discovery process has significant advantages relative to Systematic Evolution of Ligands by Exponential Enrichment (SELEX) approaches.

Specialty Nucleotides

Chemical diversity enhances interaction between an X-Aptamer and its target. Numerous modifications have been incorporated in X-Aptamer bead-based libraries, including:
