Density gradient ultracentrifugation (DGUC) is commonly regarded as the gold standard for consistent separation of difficult ...

A new method of creating laser pulses, more than 1,000 times as powerful as those currently in existence, has been proposed by scientists in the UK and South Korea. The scientists have used computer ...

Isolation of viable mononuclear and polymorphonuclear cells from blood serves as the starting point for a wide spectrum of immunology and cell biology studies. Unlike red blood cells and platelets, ...

Meselson, Stahl and Vinograd 1 first described the equilibrium density gradient technique for the examination of DNA in the analytical ultracentrifuge, and the technique has since been used to ...

Enrichment of leukocytes from blood products like buffy coat, leukocyte reduction chambers (LRSC) or leukapheresis material can be time consuming and could influence the physiology of the target cells ...

Carbon nanotubes have recently received extensive attention 1 due to their nanoscale dimensions and outstanding materials properties such as ballistic electronic conduction 2, immunity from ...

Beckman Coulter Life Sciences, a Danaher company and a global leader in laboratory automation and innovation, announces the launch of the OptiMATE Gradient Maker, a groundbreaking instrument designed ...

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in ...

The Background Oriented Schlieren Method is a very simple technique to visualize density gradients, that base on the deviation of light rays due to refractive index changes. The technique can be ...
