Buoyant


Definition:

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.

  • (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.
