Scientists Help Identify A Missing Link In Taste Perception
Working with a multidisciplinary consortium of 19 researchers from nine institutions, Monell scientists have provided critical information to identify CALHM1, a channel in the walls of taste receptor cells, as a necessary component in the process of sweet, bitter, and umami (savory) taste perception.

Laser Spotlight Reveals Machine 'Climbing' DNAThe experiments, reported in this week's Science, use laser light to generate very bright patches close to single cells. When coupled with fluorescent tags this 'spotlight' makes it possible to image the inner workings of cells fast enough to see how the molecular machines inside change size, shape, and composition in the presence of DNA.

Automation Of A Homogeneous Proximity Assay For Detection Of Residual Protein A In Biological Therapeutics
Protein A is used in affinity chromatography for therapeutic antibody purification and has been shown to leach from columns during purification of antibodies resulting in contamination. Residual Protein A in therapeutic drugs could elicit mitogenic or immunological reactions in patients.

Our integrated single-use bioreactors are designed as complete out-of-the-box jacketed systems, each paired with an integrated controller and temperature control unit (TCU).
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.

Bioprocess With The Bozenhardts is back, with a fresh episode packed with advice from Herman and Erich on the selection of filling systems for biopharmas. Listen in as the Bozenhardts give us an update on the process, logistics, and administration trends that are informing filling system decisions today, and offer direction on making choices that will prepare you for the fast-advancing therapies of tomorrow.
Bio-Rad now offers two very high capacity ion exchangers: Nuvia S, which can be used for capture and/or intermediate polishing; and Nuvia Q, which can be used for intermediate and/or final polishing.
