NIH Scientists Map First Steps In Flu Antibody Development
National Institutes of Health scientists have identified how a kind of immature immune cell responds to a part of influenza virus and have traced the path those cells take to generate antibodies that can neutralize a wide range of influenza virus strains. Study researchers from the National Institute of Allergy and Infectious Diseases (NIAID), part of NIH, were led by Gary Nabel, M.D., Ph.D., director of NIAID's Vaccine Research Center. Their findings appear online in advance of print in Nature.

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

Proven Long Life Lasers™ In Optical Particle Counters Optical particle counters (OPC) utilize light illumination and extinction to determine the presence, size, number and/or concentration of particles. Particles are typically suspended in a fluid or air, which flow through the volume that is illuminated and viewed by the detection system.

The Challenge of Measuring Total Organic Carbon In Modern Pharmaceutical Water Systems
Total Organic Carbon (TOC) is one of the quality attributes defined in the European and USA pharmacopoeias for pharmaceutical waters. Modern water treatment systems can deliver such high purity water that TOC levels can be consistently close to zero and very difficult to measure with any accuracy. This paper discusses some of the challenges when using TOC analysers to demonstrate pharmacopoeial TOC level compliance for modern water systems in the light of the ICH Q2 document from the International Conference on Harmonisation.
