Basic Properties of Soluble Interpolyelectrolyte Complexes Applied to Bioengineering and Cell Transfc IPEC formed from polyions of different length, in dilute solution can be considered as peculiar amphophilic block-copolymers. The recent data on kinetics and mechanisms of polyelectrolyte coupling and IPEC interchange reactions as well as the factors which determine interchange direction and posit

Conformation Presumption for Polysaccharide—Polylysine Complexationomponents pectate and alginates rich in L-guluronate and D-mannuronate, respectively were used. The results of the study by means of circular dichroism showed that the complex formation is governed by the stoichiometric ratio of the charges of both interacting components. The conformation of polysac

Interpolymer Complexes and their Ion-Conductioncrylic acid) (PAA), or poly(methacrylic acid) (PMAA). Hydrogen bonds between ether oxygens and carboxylic groups in the chain are formed in the complex by cooperative interaction. The ratio of the binding groups to the total of potentially interacting groups (.), and the stability constant (.) of th

Fluorescence Probe Studies of Poly(acrylic acid) Interchain Complexation Induced by High Shear Flow the PAA to be ultra-high molecular weight, low concentration (< 5 x 10. M) and at a pH range of 6–8. The mode and strength of the PAA complexation was strongly influenced by the presence of salts and cationic surfactants. Addition of salts to the shearing PAA solution disrupted the complexation, whi

Water-Soluble Biospecific Polymers for New Affinity Purification Techniquesoviding an alternative to affinity chromatography. This approach was prompted owing to certain limitations among which the difficulty to properly control the synthesis of the affinity matrix and the risk of non-specific binding of contaminants are directly related to the use of insoluble supports.

Precipitation of Proteins with Polyelectrolytes: Role of Polymer Molecular Weighting solid particles. The molecular weight has long been recognized as an important property of a polymer used for flocculation; however, the influence of molecular weight on the dual functionality of polyelectrolytes as precipitants for proteins is less clear. For a series of poly(acrylic acids) of
