Example Sentences:
(1) "Most technologies have their bright and dark side," he replies, buoyantly.
(2) Synchrony was documented by nuclear staining and fluorescence microscopy, and by determining the variation of the buoyant density of the cells during outgrowth.

(4) We have therefore termed this production of buoyant LDL in the Lpb 5.1 pigs direct buoyant LDL production.
(5) The chimeric plasmid was selected and amplified in vivo by sequential transformation of E. COLI C with the ligated mixture, selection of transformants in medium containing streptomycin plus colicin E1, followed by amplification in the presence of chloramphenicol and purification of the extracted plasmid by dye-buoyant density gradient centrifugation in ethidium bromide-CsCl solution.
