Article Analysis of Glycosylation in Biosimilars
Typically, this involves breaking the sample down into its individual monosaccharides, which can be identified and quantified by the retention time and fragmentation pattern using gas chromatography-m…

Article Optimize Column Loading Strategy to Gain Productivity in Protein Purification
Have you ever applied the concept of variable loading to gain productivity? By varying residence time (RT) over the loading phase, productivity from an affinity chromatography step can be significantl…

Article A Platform Approach for the Identity Testing of Multi-Component Cell-Culture Media
The micellar electrokinetic capillary chromatography (MEKC) was used an alternative approach to spectroscopic methods for media identification. MEKC was successfully validated and employed for the ide…

Article Implications of Cell Culture Conditions on Protein Glycosylation
For example, a high pH anion-exchange chromatography procedure with pulsed amperometric detection (HPAEC–PAD) can be used for the analysis of N-glycans. An example of this can be seen in the N-glycans…

Article Technologies and Practices Must Evolve to Meet Demand
Chromatography systems, filtration, and centrifuges received marks of “excellent” from more than 20% of the respondents (Table I). Sampling systems, single-use systems, and sterile sampling received “…

Article Comparing Protein A Resins for Monoclonal Antibody Purification
As a consequence, downstream processing must accept and handle higher titers of mAbs in harvested cell-culture fluid (HCCF), and vendors of mAb purification technologies must develop chromatography re…

Article Bioprocessing Advances in Vaccine Manufacture
This trend includes 54% considering high-capacity chromatography resins; 44%, single-use filters; 38%, automated buffer dilution systems; and 35%, single-use tangential flow filtration.Other advances …

Article In silico optimization of AAV full/empty particle separation with AIEX
Mechanistic modeling is the tool of choice to find the optimal AIEX chromatography method. We present a guiding workflow showcasing in silico process optimization of full and empty AAV5 particle se…

Article Webinar: Intensifying downstream bioprocessing with continuous technologies
We will discuss: • Intensification of capture chromatography and the benefits of coupling with viral inactivation • How a single flow through chromatography step can simplify polishing • The …
