Sartobind pico and Sartobind nano are the laboratory-scale mem-bers of the Sartobind membrane adsorber family. Accordingly, their small size and high throughput make them perfect for use on automated chromatography systems such as the popular Akta series offered by GE Healthcare Life Sciences.While both the pico and nano capsules are designed for high flow rates, the array of valves, pumps, monitors and the flow restrictor found in a typical flow path for gel chromatography can cause unacceptable pressures at the…

Currently the bio-pharmaceutical industry is heading towards cost cutting, time saving and single use manufacturing approach. This has opened up a whole new market for disposable technologies. Pre-packed disposable chromatography columns are a best fit for preclinical and clinical stage Monoclonal Antibody (mAb) production and vaccine manufacturing processes which require quick turnaround times and aggressive validation respectively. This work describes development of pre-packed and ready to use chromatography columns to meet this need in the industry. A robust packing method…

Nuvia HR-S media is a new cation exchanger designed for high resolution of closely related product impurities such as aggregates. It delivers excellent resolution, with a final aggregate content of <0.3%, and high recovery of >80% from a heterogeneous feed of monoclonal antibody aggregates and monomer. Aggregate content and recovery in the eluate were shown to be functions of the target conductivity measured at the end of collection.

This study showcases a portfolio of commercially available biopharmaceutical chromatography resins designed for the efficient purification of monoclonal antibodies. A 3-step purification process has been implemented which showed effective removal of the main contaminants, low ligand leakage, and high yields over the entire process. Eshmuno® A affinity chromatography resin was evaluated as the first step in the process. The Protein A elution pool was further purified using cation exchange chromatography. Two cation exchange resins with different selectivities were compared. The…

Natrix HD Membrane technology features a polymeric hydrogel formed within a flexible porous support matrix. The support matrix provides mechanical strength, while the hydrogel properties determine the separation chemistry of the product. An advantage of the Natrix chemistry is the ability to place virtually any functional group chemistry throughout the hydrogel polymer. Natrix HD membrane technology combines the superior binding capacity of conventional resinbased columns with the high throughput of membranes in a single-use format that eliminates costly packing, cleaning,…
