What are the normal handling conditions for polyamino acids?
All water-soluble polyamino acids (polylysine, polyornithine, polyglutamic acid, polyaspartic acid, and poly-DL-alanine) are hygroscopic and should be weighed/handled at room temperature in a dry room with the humidity level of 30% or less. All the hydrophobic polyamino acids should be weighed or handled at room temperature.
