Biotage is excited to offer PhyTip columns containing the CaptureSelect® resins from BAC BV. As the new spectrum of antibody formats evolves the current affinity ligands cannot always provide the binding and elution specificity demanded. CaptureSelect products are affinity ligands created by a proprietary technology based on Camelid derived single domain antibody fragments. These products possess a combination of unique properties such as stability, affinity, and selectivity that provide competitive benefits in terms of reduced cost of purification, higher quality product, reduced development and increased flexibility in the purification process to eliminate uncertainty, streamline protocols and ensure confidence that the final product is the intended antibody species. This is achieved through specific affinities to novel antibody domains.
