Alec Clough, 7, said excitedly that he loved the cold, before spinning off for another lap.
Thouless and Kosterlitz discovered a topological phase transition in which, at cold temperatures, spinning vortices would form in closely separated pairs and, as the temperature increased, the material would enter another phase in which the vortices split apart and travel freely.
You're out there in the cold, constantly spinning in circles, pushing people's butts around all day.
To harvest cells at various times, they were washed with cold PBS, scraped from the plate in cold PBS, spun down and finally resuspended and lysed on ice for 15 min in 300 μL of lysis buffer containing 50 mM Tris, pH 7.4, 150 mM NaCl, 50 mM β-glycerophosphate, 10 mM sodium pyrophosphate, 1% Triton X-100, 2 mM EGTA, 1 mM DTT, protease inhibitor cocktail and phosphatase inhibitor cocktail.
Now, delicately wash the lettuce in very cold water, spin or shake dry and lay out on to a handsome large platter.
After 48 72 hr, cells were harvested by scraping in cold PBS, spun down, and pellets were then snap frozen in liquid nitrogen and stored at −80°C.
EA.hy926 cells were collected, washed with cold PBS, spun down for 5 min at 500 g at 4°C, and resuspended in Sucrose Buffer (0.32 M Sucrose, 10 mM Tris HCl pH 8.0, 3 mM CaCl2, 2 mM MgOAc, 0.1 mM EDTA, 0.5% NP-40, 1 mM DTT, and 0.5 mM PMSF).
The cells were rinsed once with ice-cold PBS, spun down at 230 g for 5 min and lysed in ice-cold lysis buffer containing protease and phosphatase inhibitors (Thermo Fisher Scientific, Rockford, IL, USA), and then 2 mM phenylmethanesulfonyl fluoride (PMSF) was added.
Beads were pelleted by centrifugation at 2,500×g for 5 minutes and washed three time in ice cold 1x PBS, spinning down after each wash as described.
