Unique bond Elut PBA silica sorbent uses phenylboronic acid functionality to retain analytes via a reversible covalent bond, with high specificity and cleanliness.

• Unique phenylboronic acid sorbent
• High specificity for cis-diol compounds
• Amenable for a broad range of biomolecule applications

Bond Elut PBA is a unique silica SPE sorbent containing a phenylboronic acid functionality that can retain analytes through a reversible covalent bond. This very strong covalent retention mechanism enables high specificity and cleanliness.

The boronate group has a strong affinity for cis-diol containing compounds, such as catechols, nucleic acids, some proteins, carbohydrates, and PEG compounds. Amino alcohols, alpha-hydroxy amides, keto compounds, and others can also be retained.
