Praesto Jetted A50 is an agarose-based novel Protein A affinity resin with industry-leading performance characteristics, and utilizes a new ligand from Repligen Corporation - NGL-ImpactTM A. Praesto Jetted A50 beads are manufactured using patented 'Jetting' technology, an innovative process that produces uniform size agarose beads with a very narrow particle size distribution.

These uniform particle sizes deliver superior performance characteristics over traditional resins.
