## 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.

## Abstract The conformational changes of poly‐__N__^ε^‐glutaryl‐L‐lysine (PGL) and poly‐__N__^ε^‐succinyl‐L‐lysine (PSL) in various salt solutions were studied by use of ORD and potentiometric titration measurements. The addition of alkali metal salts to the fully ionized PGL or PSL solution cause
Poly-L-lysine exists as an a-helix at high pH and a random coil at neutral pH. When the a-helix is heated above 27ЊC, the macromolecule undergoes a conformational transition to a b-sheet. In this study, the stability of the secondary structure of poly-L-lysine in solutions subjected to shear flow, a
