What's the difference between carmine and dye?

Carmine


Definition:

  • (n.) A rich red or crimson color with a shade of purple.
  • (n.) A beautiful pigment, or a lake, of this color, prepared from cochineal, and used in miniature painting.
  • (n.) The essential coloring principle of cochineal, extracted as a purple-red amorphous mass. It is a glucoside and possesses acid properties; -- hence called also carminic acid.

  • (15) Transit time was determined by carmine and did not differ between groups.
  • (16) In the course of isolation anthocyanins, carmine, betanin, caramel and riboflavin are separated from synthetic dyes, as well as from one another, with the exception of first two, which are separated from one another by chromatography or distinguished by oxidation.
  • (17) Intestinal transit times in children less than 3 years old with gastroenteritis were measured using carmine suspension and radioopaque pellets.
  • (18) The results indicate that cochineal lacks carcinogenicity in mice and are consistent with those of in vitro short-term assays of cochineal and of carminic acid, an active principle of cochineal.
  • (19) When injected with indigo carmine, the vessels localized by the hydrogen-induced current impulses filled the entire anterior spinal artery from the low thoracic to the sacral region, whereas injection of the other vessels did not show filling.
  • (20) Andreotti was also accused of having ordered the murder of a rightwing journalist, Carmine Pecorelli, in 1979.

Dye


Definition:

  • (v. t.) To stain; to color; to give a new and permanent color to, as by the application of dyestuffs.
  • (n.) Color produced by dyeing.
  • (n.) Material used for dyeing; a dyestuff.
  • (n.) Same as Die, a lot.

Example Sentences:

  • (1) The most successful dyes were phenocyanin TC, gallein, fluorone black, alizarin cyanin BB and alizarin blue S. Celestin blue B with an iron mordant is quite successful if properly handled to prevent gelling of solutions.

  • (4) While the reduced form of the "derived" polyphenolic compounds, generated during tissue homogenization, appeared to enhance dye binding with bovine serum albumin, their influence on the protein assay directly in crude homogenates was extremely diverse.
  • (5) To selectively stain polyanionic macromolecules of growth plate cartilage and to prevent artifacts induced by aqueous fixation, proximal tibial growth plates were excised from rats, slam-frozen, and freeze-substituted in 100% methanol containing the cationic dye Alcian blue.
  • (6) This dye is concentrated and secreted by the parietal cells.
  • (7) The rhodamine 123-induced growth inhibition was partially reversed by treating the dye-pre-exposed infected erythrocytes with the proton ionophore carbonyl-cyanide m-chlorophenylhydrazone, which dissipates transmembrane proton gradients.
  • (8) The duration of electrophoresis was based on the migration of a marker dye for a predetermined distance.
  • (9) Effects of fixation with glutaraldehyde (GA), glutaraldehyde-osmium tetroxide (GA-OsO(4)), and osmium tetroxide (OsO(4)) on ion and ATP content, cell volume, vital dye staining, and stability to mechanical and thermal stress were studied in Ehrlich ascites tumor cells (EATC).
  • (10) By using pH- or Ca(2+)-sensitive dyes and recording at the ion-sensitive and -insensitive (isosbestic) wavelengths, the method can measure both cell volume changes and intracellular ionic activities.
