TGF-β1 and SIRT1 levels of kidney homogenized tissue were measured by ELISA method (Zellbio, Germany). In this case, the measurement was based on the reaction between the antigen and the antibody, and finally the adsorption was read at 450 nm. After placing the adsorption and concentration of standard solutions in Excel program, the standard curve was prepared. Concentration of the samples was determined based on the adsorption using the standard curve linear Eqs. [40 (link)–42 (link)].
