Solution Properties of Phycocyanin. III. Studies of the Sedimentation Equilibrium of Phycocyanin [PDF]

open access: yesBulletin of the Chemical Society of Japan, 1975
Abstract The dissociation-association behavior of phycocyanin has been studied by sedimentation-equilibrium measurements under various pH and ionic-strength conditions. The weight-average molecular weight of phycocyanin changed according to the changes in concentration of the solute.

The In Vitro Anti-Tumor Activity of Phycocyanin against Non-Small Cell Lung Cancer Cells

open access: yesMarine Drugs, 2018
Phycocyanin, a type of functional food colorant, is shown to have a potent anti-cancer property. Non-small cell lung cancer (NSCLC) is one of the most aggressive form of cancers with few effective therapeutic options.

Characterization of R-phycocyanin. Chromophore content of R-phycocyanin and C-phycoerythrin.

open access: yesJournal of Biological Chemistry, 1975
R-phycocyanin was purified from two independent isolates of the unicellular red alga Porphyridium cruentum. At pH 7.0 the protein sediments as a single component with s 20,w of 5.98 S (at 2 mg/ml, gamma/2=0.02). Over a protein concentration range of 0.2 to 0.5 mg/ml (gamma/2=0.16), sedimentation equilibrium gave a molecular weight of 103,000 +/- 6,000 ...

Circular Dichroism of Chromopeptides from Phycocyanin [PDF]

open access: yesZeitschrift für Naturforschung C, 1983
The circular dichroism of bilipeptides from Spirulina geitleri phycocyanin is strongly solvent and pH dependent. Maximum optical activity has been observed in aqueous solutions containing urea (8 ᴍ). In aqueous buffer, a sign reversal occurred upon the change from neutral to acidic pH; in methanolic solutions shows the optical activity a strong pH ...
