Fig. 1From: Reversible bacterial immobilization based on the salt-dependent adhesion of the bacterionanofiber protein AtaAEffect of ionic strength on the adhesion of purified AtaA PSD. a Adhesion of AtaA PSD as a function of ionic strength. Amounts of AtaA PSD adhered to wells of a polystyrene (PS) or a glass 96-well plate were quantified by ELISA with anti-AtaA antiserum. Data are expressed as mean ± SEM (n = 3). b Ion-dependent adhesion of AtaA PSD was analyzed using QCM. Arrows indicate the addition of AtaA PSD dissolved in dH2O and KCl solutionBack to article page
