title: Sarkosyl is a good regeneration reagent for studies on vacuolar-type ATPase subunit interactions in Biacore experiments.
abstract: Biacore is widely used for studies on protein-protein interaction in which regeneration is one of the most important steps. Here we introduce the anionic detergent sodium lauroyl sarcosinate (sarkosyl), which works satisfactorily as a regeneration reagent. After regeneration by the mild detergent, the subsequent binding experiment was reproducible without any degradation of the ligand. This regeneration condition can be employed for diverse combinations of ligand-analyte binding interactions and optimized as required.
