This poster highlights the Chromacassette® Technology: First practical modular chromatography platform. Supported-bed enables packing of any resin bead. Constant bed permeability, independent of resin compressibility even at V > 1000 cm/hr. Truly linear scalable. Eliminates packing methods and equipment. New operating domains and resin design are now possible for both bind and elute and flow-through. Hyper-Productive™ process enabling for single-use chromatography. PD devices will be available early 2018.

Four Protein A resins from leading industry vendors, including Amsphere™ A3, were screened for use in a capture step for a Herceptin biosimilar. Multiple parameters were assessed for their performance against the platform resin. Initially, a dynamic binding capacity (DBC) determination was made using a standard 4-minute residence time (RT) using purified protein. Performance of the resins were then screened for recovery and purity using harvested cell culture fluid (HCCF) where the MAb load was 80% of DBC at 10%…
