What's the difference between quench and quenchless?

Quench


Definition:

  • (v. t.) To extinguish; to overwhelm; to make an end of; -- said of flame and fire, of things burning, and figuratively of sensations and emotions; as, to quench flame; to quench a candle; to quench thirst, love, hate, etc.
  • (v. t.) To cool suddenly, as heated steel, in tempering.
  • (v. i.) To become extinguished; to go out; to become calm or cool.

Example Sentences:

  • (1) The extreme quenching of the dioxetane chemiluminescence by both microsomes and phosphatidylcholine, as a model phospholipid, implies that despite the low quantum yield (approx.
  • (2) The drug is extracted from serum or urine with ethyl acetate, separated by TLC, and determined by fluorescence quenching densitometry.
  • (3) Formation of a complex between alpha-tocopherol or its analogues in the excited state and fatty acids or their hydroperoxides has been suggested basing on the fluorescence quenching experimental data.
  • (4) Quenching of intrinsic fluorescence of (Ca2+-Mg2+)-ATPase by acrylamide, performed in the presence of Ca2+, gave evidence for a single class of tryptophan residues with Stern-Volmer constant (KSV) of 10 M-1.
  • (5) The 23Na double-quantum signal was quenched in both the extracellular and the intracellular compartments with increasing concentration of Li in each compartment, along with an increase in the 23Na T1 both intra- and extracellularly.
  • (6) Binding increases the fluorescence intensity of Tyr-49 by 130% while the fluorescence of the hormone tyrosine is almost completely quenched.
  • (7) Addition of 2,6-dimethylbenzoquinone caused quenching of these absorbance changes.
  • (8) These observations lead to the hypothesis that acidosis quenches fluorescence in distal skin flaps.
  • (9) The degree of quenching was accurately predicted by a simple relation derived in this paper, as well as a more complex equation previously developed by Tweet, et al.
  • (10) Subtilin may slightly enter the hydrophobic core as suggested by tryptophan fluorescence quenching and liposome fusion experiments.
  • (11) Greater than 99% of the polymerization reaction products were quenched by the addition of 2.0 mM ascorbate.
  • (12) Acoustic probe-based assays can enhance assay and laboratory efficiency through testing for multiple analytes in a single sample or increasing available binding surface area (by using probe and well surfaces simultaneously), and by eliminating quenching.
  • (13) The second-order rate constants appear to be at least 3 orders of magnitude lower than the second-order constants for quenching of the fluorescent probes; this is taken as a clear indication that ubiquinone diffusion is not the rate-determining step in the quinone-enzyme interaction.
  • (14) Accessibility to iodide was much lower, as was the rate of quenching by iodide, adding support to the conclusions from acrylamide quenching.
  • (15) An ATP-dependent, N-ethylmaleimide-inhibitable, 3,3',4',5-tetrachlorosalicylanilide-reversible, and chloride-attenuated quench of bis(1,3-dibutylbarbituric acid-(5] pentamethinoxonol fluorescence was seen, consistent with net transfer of positive charge into the vesicles.
  • (16) Quenching data indicated that five out of 22 tryptophans in CBH are surface-localized and are available for quenching with both KI and acrylamide, and three other tryptophans are buried and are available only to acrylamide.
  • (17) Acid quenching of a stiochiometric reaction between Ac(= S)CoA and citrate synthase following the transient quantitatively regenerates Ac(= S)CoA, indicating carbon-carbon bond formation had not yet occurred.
  • (18) The pulsed laser photolysis products of the charge-transfer quenching reaction were examined.
  • (19) The highest yield of amino acids with the quench reaction was 9 x 10-7 molecules per erg of input energy.
  • (20) Tris-washed chloroplast enriched in the photosystem II reaction center species Z+Q- and ZQ- are nearly four times more sensitive to nitrobenzene quenching than those enriched in Z+Q.

Quenchless


Definition:

  • (a.) Incapable of being quenched; inextinguishable; as, quenchless fire or fury.

Example Sentences:

  • (1) Still, they are bust: and while they say they were suffocated by demand, all charities face quenchless need.
