C acid (PFOA), cells inside the absence or presence of rising concentrations of (A) perfluorooctanoic acid (PFOA), for 1 min at 37 within a sodium-containing buffer and corrected for protein. Following conversion on the (B) perfluorononanoic acid (PFNA), (C) perfluorodecanoic acid (PFDA). Uptake was measured for (B) perfluorononanoic acid (PFNA), oror (C) perfluorodecanoic acid (PFDA). Uptake was measured information to percent of manage, IC50 values were calculated using GraphPad Prism V9 utilizing the “One for 1 min atC within a sodium-containing buffer and corrected for protein.

Inhibition Kinetics of NTCP-Mediated Taurocholate Transport for PFOA, PFNA, and PFDA To PFDA figure out the kind of inhibition demonstrated in Figures 1 and 2, we performed To ascertain the type of inhibition demonstrated in Figures 1 and two, we performed inhibition kinetics by measuring the transport of escalating Figures 1 and two, we performed To identify by form of inhibition demonstrated in concentrations of taurocholate inhibition kinetics the measuring the transport of increasing concentrations of tauroinhibited by 0, 10, and measuring either PFOA, PFNA, or PFDA.
