Biologically Active Water-insoluble Protein Polymers

Biologically Active Water-insoluble Protein Polymers 1. THEIR USE FOR ISOLATION OF ANTIGENS AND ANTIBODIES

Insoluble antigen and antibody derivatives were obtained when ethyl chloroformate was added to solutions of antigen or antibody. Evidence has been obtained to show that polymerization has occurred and that the protein molecules are linked covalently to one another. The immunoadsorbent properties of these insolubilized proteins were investigated. They were found to be efficient, specific, and st...

BIOLOGICALLY ACTIVE SYNTHETIC POLYMERSt

The 1:2 divinyl ether-maleic anhydride cyclic alternating copolymer (DIVEMA) shows a wide variety of biological activities. It has antitumor activity; it induces the formation of interferon; it has antiviral, antibacterial, and antifungal activity; it is an anticoagulant and an anti-inflammatory agent. DIVEMA is an immunopotentiator; it increases the rate of phagocytosis, it activates macrophag...

Novel Biologically Active Phenolic Polymers from Different Species of Genera Symphytum and Anchusa (Boraginaceae)

The presented special communication summarizes data concerning novel caffeic acid-derived polyether from the species of two genera (Symphytum and Anchusa) of Boraginaceae family Symphytum asperum, S. caucasicum, S. officinale and Anchusa italica and structure elucidation of its main structural element. The high-molecular fractions were isolated from crude polysaccharides by ultrafiltration on m...
