The Providence mascot, with its creepy nonsmile facial expression, shook Aresco's hand.
All bacteria strains were grown overnight at 37°C in Luria-Bertani (LB) broth with carbenicillin or chloramphenicol (Sigma-Aldrich, St Louis, MO) to maintain GFP expression while shaking, subcultured at a dilution of 1∶33 in fresh LB medium and incubated while shaking at 37°C for 3 to 4 hours to obtain exponentially growing bacteria.
For expression in shaking flasks, 100 mL 2xTY medium + 100 μg/mL ampicillin + 100 mM glucose were inoculated 1 20 with an overnight culture of XL1-Blue MRF' containing the appropriate vector and grown at 37°C and 250 rpm for 2 h.
But as your audience nod their heads enthusiastically, you adopt a pained expression and shake yours.
The other half was centrifuged, resuspended in the same medium without tryptophan for PRK expression, and shaken in parallel (solid squares).
He looked at me with a surprised expression and shook his head.
One potential alternative explanation for the biphasic HTR is that high levels of 5-HT2A activation may produce competing behaviors that interfere with expression of head shaking.
By the time he led 3-0 in the third set, Murray had dropped his familiar hang-dog expression, even smiling and shaking his fist after one of his crosscourt shots caught Nieminen flat-footed.
Briefly, after BRCA1 expression was induced by shaking for six hours at 30°C in GAL, cells were fixed in formaldehyde for 1 hr at RT, recovered by centrifugation, resuspended in 50 mM phosphate-buffered formaldehyde plus sorbitol (1.2M) and fixed a further two hours at RT.
Expression was performed in shaking cultures in DYT medium supplemented with appropriate antibiotics, trace elements (Studier) and 0.2% (w/v) glucose.
