Purpose of iodoacetamide
Web2-Iodoacetamide (Iodoacetamide), an alkylating agent, is a commonly used agent for alkylation of cysteine during sample preparation for proteomics [1] [2] . 2-Iodoacetamide (2.0-10 mg; drinking; daily; 20-93 days) feeding always produces chronic deep ulcers in the secretory part of the rat stomach [2]. MCE has not independently confirmed the ... WebHydrophobic tags, derived from iodoacetamide, were synthesized, characterized, and utilized to alkylate peptide E-76, a known inhibitor of coagulation factor VIIIa, and two other cysteine containing peptides. The electrospray response of each tagged peptide was compared against the same peptide alkylated with iodoacetamide. E-76 peptide alkylated with the …
