(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.
Pigmentation
Definition:
(n.) A deposition, esp. an excessive deposition, of coloring matter; as, pigmentation of the liver.
Example Sentences:
(1) The results also suggest that the dispersed condition of pigment in the melanophores represents the "resting state" of the melanophores when they are under no stimulation.
(2) Differences between the albino vs pigmented strains were observed following injections of saline.
