Reactions were terminated by filtration through glass fibre membranes (printed Filtermat A, Wallac) using a Combi cell harvester (Skatron) and ice-cold 50 m m Tris-HCl (pH 7.5).
After overnight culture, the plates were stored at -80°C for membrane printing.
And underneath the keys of computer keyboards are membranes with printed circuits that sense when a key is pressed.
Cal Poly is looking at revolutionizing desal tech, proposing to use printed membranes, which move seawater a million times faster than current desalination methods that utilize porous filters, but that technology is still 10 years out.
Using the proposed minimal spot distance of 2 mm, a 10 cm × 7 cm nylon membrane can accommodate 384 genes printed in duplicate, and multiple membranes can be used in the same hybridisation reaction.
The company's industrial business, which makes roofing membrane and platforms for printed circuit boards, is flying high.
Bhalla and co-workers looked at the effect of atrazine on currents generated by PSII reaction centres or BBY particles (PSII-enriched membranes) adhered to screen printed gold electrodes, reporting an IC50 of 49 nm and LOD of 1.15 nM (Bhalla and Zazubovich, 2011).
For phosphoproteomic analysis the cell lysates were printed onto nitrocellulose membrane slides.
9,600 cDNA clones were printed on the membrane cDNA arrays.
