Researchers 'Switch Off' Neurodegeneration In Mice
Researchers at the Medical Research Council (MRC) Toxicology Unit at the University of Leicester have identified a major pathway leading to brain cell death in mice with neurodegenerative disease. The team was able to block the pathway, preventing brain cell death and increasing survival in the mice.

Microbial Fermentation In Single-Use Xcellerex™ XDR-50 MO Fermentor SystemThis application note describes the performance of a single-use Xcellerex XDR-50 bioreactor system when used in cultivations of E. coli and of modified Pseudomonas fluorecsens (P. fluorescens) producing a monoclonal antibody (MAb). Both the achieved microbe densities and product yield were shown to be consistent with the performance of conventional stainless steel systems.

Removal Of Host Cell Proteins During Monoclonal Antibody Purification
Protein A chromatography is a widely used and highly successful method of purifying recombinant monoclonal antibodies. However, since Protein A has high affinity for antibodies, harsh conditions such as low pH are often required to elute monoclonal antibodies from Protein A affinity columns. By 3M Purification Inc

Macro-Prep hydrophobic interaction chromatography (HIC) media are methacrylate-based, 50 µm beads used for protein, polypeptide, enzyme, and nucleic acid purification.
CHT is a leading purification medium of biomolecules in today’s demanding downstream process industry. Its mixed-mode support offers unique selectivities and often separates biomolecules that appear homogeneous with other chromatographic methods. The diverse binding capabilities of CHT for host cell proteins, leached protein A, antibody dimers and aggregates, nucleic acids, and viruses allow its use at any stage from initial capture to final polishing.
