The results of the drug addition and removal tests suggest that mangiferin inhibits the late event in HSV-2 replication. Kobe-Gakuin University, Japan. New saponins from Mangifera indica. This chapter provides an updated report of carotenoprotein-related research. Carotenoproteins have been isolated, purified, and characterized from the ectoderm, exoskeleton, eggs, and ovaries of marine invertebrates, especially crustaceans.
Studies are currently in progress to purify and characterize the protein.
This is the first successful isolation of a vertebrate carotenoprotein. The isolation of carotenoproteins is generally by standard techniques of protein chemistry. Purification, crystallization of the complex, and reconstitution of apoprotein and carotenoid components have been achieved for some crustacean carotenoproteins. The complex is very sensitive to bright light and to temperatures above that of refrigeration. However, it is best preserved in solutions of high ionic strength or as a precipitate in strong ammonium sulfate solutions.
