Cell Culture Protein Surface Coatings Market will Going to be Worth US$ 623.4 Mn by 2020

A handful of well-entrenched large companies dominate the global market for cell culture protein surface coatings market. Greiner Bio-One International AG, Corning Incorporated, Sigma-Aldrich Corporation, Merck Millipore, and Thermo Fisher Scientific, Inc. are to name a few of them. Stiff competition exists between these players on account of their constant efforts to come up with more effective products. To reach their dominant positions, they have also banked upon mergers and acquisitions and partnerships. A recent report on the market for cell culture protein surface coatings finds that it would reach a value of US$623.4 mn by the end of 2020. Depending upon the source of protein, the market has been classified into plant protein, animal protein, human protein, and synthetic protein. Among these, the synthetic protein accounts for considerable market share and is rising at an impressive pace. This is primarily on account of surging demand for animal-free surface coatings, particularly in the nations of North America and Europe. On the basis of geography, North America accounted for a substantial share in the market for cell culture protein coatings. The superior healthcare in...

Overcoming Challenges in High-Speed Centrifugation Experiments

An interview with William Arteca, to discuss the how centrifuges are used in Neuroscience research and introduces a new product for high-speed lab applications, conducted at SfN 2018 by Alina Shrourou, BSc. Neuroscience research is very molecular biology based, so there is a lot of sample preparation and other biology-based analytical techniques, such as western blot and gel electrophoresis. A centrifuge is an essential part of any lab, especially in molecular biology, because it is routinely used in sample preparation. With trial and error, you develop your own procedure and methods. With standard operating procedures, you follow what you find online or from other scientists. Some of the main challenges are determining what speed to do it at and determining if the sample is temperature sensitive. This is important, in order to ensure that it doesn’t degrade while you’re centrifuging it. In addition, a centrifuge is a very sensitive machine when it’s not used correctly and so one of the biggest challenges can be determining the rotor size and what attachments to use for it, such as swing out, fixed angle, and tube size. We are launching our centrifuge, the Fron...

Dense suspensions of swimming bacteria are living fluids, an archetype of active matter. For example, Bacillus

Dense suspensions of swimming bacteria are living fluids, an archetype of active matter. For example, Bacillus subtilis confined within a disc-shaped region forms a persistent stable vortex that counterrotates at the periphery. Here, we examined Escherichia coli under similar confinement and found that these bacteria, instead, form microspin cycles: a single vortex that periodically reverses direction on time scales of seconds. Using experimental perturbations of the confinement geometry, medium viscosity, bacterial length, density, and chemotaxis pathway, we show that morphological alterations of the bacteria transition a stable vortex into a periodically reversing one. We develop a mathematical model based on single-cell biophysics that quantitatively recreates the dynamics of these vortices and predicts that density gradients power the reversals. Our results define how microbial physics drives the active behavior of dense bacterial suspensions and may allow one to engineer novel micromixers for biomedical and other microfluidic applications. Dynamic, biologic systems are often driven by organized forces produced by small constituent molecules or cells. For example, the motion...
