Staphylococci are a major cause of infections associated with indwelling medical devices. Biofilm formation on these devices adds to the antibiotic resistance seen among clinical isolates. RNAIII-inhibiting peptide (RIP) is a heptapeptide that inhibits staphylococcal pathogenesis, including biofilm formation, by

Reaction conditions were defined for the selective quantitative derivatization and fluorophore labeling of phosphoserine residues on peptides and proteins. Phosphoserine was derivatized with 1,2-ethanedithiol using a modification of the reaction conditions defined by R. C. Clark and J. Dijkstra (1967)
