ABSTRACT:
The present invention relates generally to the field of analyzing proteins and more specifically to the reduction and alkylation of protein samples during protein analysis. A novel composition and method for reducing and alkylating proteins is disclosed. A novel reagent including a combination of a volatile reducing agent, a volatile alkylating agent, and a volatile solvent is used for a one-step reduction and alkylation of proteins allowing the protein sample to remain in the same container during the reduction and alkylation processes.
