WebBiotin polyethyleneoxide (PEO) iodoacetamide group reacts specifically with reduced thiols at pH 7.5 - 8.5. Peptides and small molecules containing thiol groups may also be labeled using this reagent. The biotin PEO iodoacetamide enables tagging of cysteine residues and conjugation to sulfhydryls in proteins making it useful in proteomics ... WebDec 12, 2009 · Following conjugation to biotin-iodoacetamide, biotin-maleimide, or fluorescein-maleimide, the proteins were diluted in 15 mL 100 mM sodium acetate (pH 5.2) and concentrated to 250 μL as described above. This step was repeated once with 15 mL 100 mM sodium acetate (pH 5.2) and subsequently twice with 15 mL PBS to remove … greenland film cda
