RENBP and urinary bladder neoplasm: Hence, for the analysis of T24 bladder tumor cell proliferation, concentrations of TY = 40 μM and 20 μM were selected, with which complexes with Ag+ (TY-Ag = 1:0.5 molar ratio) and in some experiments additionally with albumin (BSA-TY = 1:10 molar ratio) were prepared.
