What's the difference between quadroxide and tetroxide?
Quadroxide
Definition:
(n.) A tetroxide.
Example Sentences:
Tetroxide
Definition:
(n.) An oxide having four atoms of oxygen in the molecule; a quadroxide; as, osmium tetroxide, OsO/.
Example Sentences:
(1) 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).
(2) The renal tissue was fixed with a mixture of buffered picric acid-paraformaldehyde-glutaraldehyde and immunostained with the peroxidase-antiperoxidase method for the electron microscope with the following steps: antikallikrein antiserum, anti-IgG serum, peroxidase-antiperoxidase complex, 3-3' diaminobenzidine-H2O2, and post-staining with osmium tetroxide.
(3) It was also found that tritium release also occurred, although to a lesser extent, when tissues were fixed in glutaraldehyde or osmium tetroxide using collidine as a buffer, and this release was not significant when collidine was applied to previously fixed tissues.
(4) In accordance with the physiological experiments, electronopaque pyroantimonate precipitate containing calcium was found in the lumina of caveolae, but not in any intracellular structures close to the plasma membrane, when the relaxed fibers were fixed in a 1% osmium tetroxide solution containing 2% potassium pyroantimonate.
(5) The addition of oxalate to a suspension of rabbit peritoneal neutrophils before fixation with glutaraldehyde and postfixation with osmium tetroxide-antimonate greatly enhanced the amount of calcium antimonate precipitate subsequently detectable with the electron microscope.
(6) Intravascular fat in tissue postfixed in osmium tetroxide, embedded in epoxy or paraffin, and stained with toluidine blue, hematoxylin, or Oil Red O is more easily visualized than in frozen tissue that is stained with Oil Red O.
(7) Mitotic cells were selectively removed from the cultures with 0.2 per cent trypsin and fixed in either osmium tetroxide or glutaraldehyde followed by osmium tetroxide.
(8) Glutaraldehyde-fixed testes were stained "en bloc" with the Ur-Pb-Cu technique of Thiéry and Rambourg ('76) or post-fixed and stained with the osmium tetroxide-potassium ferrocyanide method of Karnovsky ('71).
(9) Insertion of 28 alternating AT residues at the EcoRV site of pBR322 generates an site hypersensitive to osmium tetroxide modification, that does not serve as a transcription start site.

(11) It uses carbohydrazide as an osmium bridging agent and both osmium tetroxide and uranyl acetate as electron staining agents.
(12) Parallel microsamples were fixed with osmium tetroxide and with glutaraldehyde followed by osmium tetroxide as previously used in this laboratory for the preservation of energy-linked mitochondrial configurations.
(13) A combination of 2% osmium tetroxide-2% uranyl acetate or 2% gallic acid alone resulted in optimum fixation as ascertained by least extraction of radiolabels.
(14) The optic nerves of common goldfish acclimated to 5 and 25 degrees C were fixed with glutaraldehyde in either phosphate buffer or PIPES with EGTA, post-fixed with osmium tetroxide, and examined by electron microscopy.
(15) 7.5% PVP was included in all steps in the procedure before post-fixaiton in osmium tetroxide.
(16) It was recently reported that sequential block staining of tissue with ferrocyanide-reduced osmium tetroxide and lead aspartate produced excellent contrast for EM autoradiography, with sections relatively free of lead precipitate.
