Dye


Definition:

  • (18) This protein which we call CBP-58 bears similarities to the endoplasmic reticulum protein, calreticulin, in that it has a pI of 4.7 containing approximately 30% glutamate and aspartate, has a high capacity for calcium, and stains blue with the carbocyanine dye, 'Stains-all'.
  • (19) Minced and triturated fragments from the spinal cord of normal rat fetuses (15-18 days gestation) labeled with the fluorescent dye fast blue (FB) were successfully transplanted into juvenile myelin-deficient rat spinal cord under direct observation.
  • (20) In vitro, the soluble core PEI and membrane both bound reactive substances of limited aqueous stability, such as from [14C]N-methyl-N-nitrosourea ([14C]NMU), and aqueous stable dyes of molecular weight up to 1000.

Substrate


Definition:

  • (n.) A substratum.
  • (a.) Having very slight furrows.
  • (v. t.) To strew or lay under anything.

Example Sentences:

  • (1) 5-HT thus appears to be the preferred substrate for uptake into platelets and for movement from cytoplasm to vesicles.

  • (3) These results demonstrate that increased availability of galactose, a high-affinity substrate for the enzyme, leads to increased aldose reductase messenger RNA, which suggests a role for aldose reductase in sugar metabolism in the lens.

  • (5) Manometric studies with resting cells obtained by growth on each of these sulfur sources yielded net oxygen uptake for all substrates except sulfite and dithionate.

  • (7) The observed relationship between prorenin and renin substrate concentrations might be a consequence of their regulation by common factors.
