What's the difference between bromide and perbromide?

Bromide


Definition:

  • (n.) A compound of bromine with a positive radical.

Example Sentences:

  • (1) The effect of ipratropium bromide administered at two dosage levels, 40 and 80 mug, isoproterenol, 150 mug, and placebo using a metered dose inhaler was evaluated in ten adult patients with asthma in a double-blind, crossover study.
  • (2) A semiautomated colorimetric assay (MTT assay), based on the ability of live cells to reduce a tetrazolium-based compound, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT), to a purplish colored formazan product that can be measured spectrophotometrically, has recently been adapted for use in drug sensitivity analysis of cultured human tumor cell lines.
  • (3) Samples of raw cereals imported in Italy and of other foodstuffs that can be treated with bromine-containing fumigants were analysed for the total bromide content.
  • (4) Uptake into arterial collagens and release of labeled hydroxyproline were then measured after 2.5 h. The relative amounts of types I and III collagens were assessed from the levels of cyanogen-bromide-derived peptides alpha 1(I)CB8 and alpha 1(III)CB5, respectively, after sodium dodecyl sulfate polyacrylamide gel electrophoresis.
  • (5) The use of SDS-polyacrylamide gel electrophoresis of the cyanogen bromide derived peptides from fibrous cartilage collagens enabled to calculate type I to type II collagen ratio in this tissue.
  • (6) The patients received no premedication or basic anaesthesia and relaxation was obtained using pancuronium bromide.
  • (7) The inhibitory phase was blocked by atropine and the excitatory phase was eliminated by tubocurarine chloride, hexamethonium bromide or pindolol.
  • (8) We conducted a randomized, double-blind, placebo-controlled study of the effect of a new anticholinergic agent, oxitropium bromide, on bronchoconstriction induced by inhaled propranolol in seven subjects with mild asthma 24 to 39 yr of age.
  • (9) Ten copies of HIV-1 DNA could be detected by PCR-EIA (42 fluorescent units with a background of 18 fluorescent units) compared with a detection limit of 1000 copies by ethidium bromide-stained agarose gel.
  • (10) Because previous work has shown that radioisotope release from parasites may be nonspecific, separate experiments were performed to determine the cytotoxicity of LAK cells against antibody-coated trophozoites by using ethidium bromide-acridine orange staining to assess effector cell damage.
  • (11) Key intermediate of the synthesis was 2-formyl-estradiol (2) which was prepared in quantitative yield through reaction of the phenoxymagnesium bromide of estradiol with formaldehyde in the presence of HMPA.
  • (12) The relative standard deviations for bromide at 10(-7) M and for iodide at 10(-8) M concentration were 1.9% and 3.0%, respectively, using a 10-mL sample for the determination without preconcentration.
  • (13) This enhancement of the release of radioactivity was inhibited by phospholipase A2 inhibitors, quinacrine (1 mM) and p-bromophenacyl bromide (10 microM), suggesting that polyethylenimine and polyallylamine activates phospholipase A2 to generate arachidonate and its metabolites.
  • (14) Plasmid sequences were readily observed by ethidium bromide staining of cellular DNA after restriction endonuclease digestion and agarose gel electrophoresis.
  • (15) Cytochemical localization of ovoperoxidase activity with diaminobenzidine revealed almost a total lack of staining of FEs from bromide-substituted sea water.
  • (16) Cells were exposed to chlorhexidine, hydrogen peroxide and sodium hypochlorite for 15 min and cell viability was assessed 24 h later with a colorimetric assay which utilizes the tetrazolium salt 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT).
  • (17) The sequence was obtained from analysis of peptides isolated from chymotryptic, cyanogen bromide, and limited acid cleavages of the protein.
  • (18) The latter compounds were reduced with lithium aluminium hydride to the respective amines (II a-c) and then N-alkylated by reaction with 2-propynyl-, 2-butynyl- or 2,3-butadienyl bromides to the corresponding amines (III a-j).
  • (19) When the detergents with aliphatic hydrophobic residues were compared, a cationic detergent cethylmethylammonium bromide (CTAB) was more toxic than non-ionic or anionic detergents.
  • (20) Cyanogen bromide cleavage of the 145000 subunit produced a single peptide of Mr 75000.

Perbromide


Definition:

  • (n.) A bromide having a higher proportion of bromine than any other bromide of the same substance or series.
