Lower panel shows Coomassie staining of a SDS-PAGE gel loaded with the same whole cell extract samples to control for equal protein extraction efficiency.
Now, mosquitoes are sent through a tissuemizer, a lab device that shakes vials of mosquitoes until they're nothing more than liquid to extract samples for testing.
It will also build a drill that will bury down beneath the surface and extract samples.
Scientists were initially reluctant to use a drill, designed to extract samples for chemical analysis, and other moving instruments, in case doing so would turn Philae upside down.
Sculptural stations are scattered in between, like so many clunky science-fair booths — at one, a scoring saw cracks open the Armory's floor to extract samples of Martian geology (wooden floorboards), at another, rice and beans are prepared for the astronauts' meals.
The extract samples were analysed by TLC, TLC-densitometry, GC and HPLC methods.
In the first column were added 50 µL of diluted extract (samples sterility control).
After 12 h the extract samples were centrifuged at 3000 rpm for 10 min.
The purpose of this study was to compare methods of preparing complex botanical extract samples prior to metabolomics profiling.
Milk and chicken extract samples were spiked with various concentrations of these pathogens and were used to challenge the system.
Firstly, Fourier transform infrared and thermogravimetric analysis confirmed chemical differences on structure, stability and purity of the evaluated extract samples.
