Electrophoretic behavior of poly‐L‐glutamic acid and poly‐L‐lysine

Abstract

Abstract Two electrophoretic components have been detected on the ascending boundary in unbuffered solutions of polyglutamic acid and polylysine under certain experimental conditions. If the conditions are favorable to aggregation, another maximum, the third in order, is formed on this boundary. We attribute this maximum to the formation of aggregates. The behavior of both boundaries and all components at various pH, concentrations, and temperature of solutions and at different molecular weights of polymers was described.
