Modern 3D printers enable not only rapid prototyping, but also high-precision printing - microfluidic devices with channel diameters of just a few micrometres can now be readily assembled using this technology. Such devices ...

The α-humulene synthase from Zingiber zerumbet Smith was expressed as a polyhistidine-tagged protein in an E. coli BL21(DE3) strain. Induction time and inductor (isopropyl-β-D-thiogalactopyranoside) concentration were ...
