Highly Cross Linked Agarose Protein A Affinity Resin
Our always-ready technical support and service teams go the extra step to be your most trusted resource. We're here for you.
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.
