Use of ScreenExpert RoboColumns for High Throughput Study of Loading Conditions on HyperCel™ STAR AX and MEP HyperCel Sorbents for MAb Purification in Flow-Through Mode

The use of HyperCel STAR AX and MEP HyperCel sorbents for MAb polishing provides efficient contaminant removal. A study to screen loading conditions for MAb purification in flow-through mode on MEP HyperCel and HyperCel STAR AX sorbents was conducted using 200 μL ScreenExpert RoboColumns. The study demonstrates the suitability of ScreenExpert RoboColumns for scale down evaluation of chromatographic parameters, and the good consistency with data obtained on 1 mL PRC prepacked columns. ScreenExpert RoboColumns allow loading of high sample volume…

Implementation of Mustang® Q Membrane Chromatography as a Polishing Step (Residual DNA Removal) in Monoclonal IgG1 Production from CHO Cell Culture

In collaboration with ProBioGen AG, Berlin, Germany, Mustang Q membrane chromatography was evaluated as a polishing step following protein A affinity and cation exchange chromatography to remove residual host cell DNA during a Monoclonal antibody (MAb) purification process at 250 L cell culture production-scale. Data indicated efficient DNA clearance by the Mustang Q membrane chromatography step during the process (96%). Additionally, contribution of the Mustang Q membrane chromatography polishing step to HCP removal was shown. Based on a virus-spiking scale-down…

New ambr® bioreactor systems enhanced with software for Design of Experiments (DoE)

Sartorius Stedim Biotech (SSB) today announced the 2015 version of the ambr® systems (ambr® 15 and ambr® 250) will be supplied with integrated BioPAT® MODDE Software for Design of Experiments (DoE), powered by Umetrics. This will allow bioprocess scientists to easily implement DoE into their work flow for simpler process optimisation and scale-up to larger single-use BIOSTAT® pilot and manufacturing scale bioreactors, making bioprocess development faster and more cost-effective. The integrated DoE software will enable scientists to quickly establish a…
