Evaluation of KIM-1 stability in urine matrix. (A) Recovery of KIM-1 in urine samples stored at RT, 4°C, −20°C, and −80°C over different length of times. The plotted data are the means ± SD values of three samples. (B) Stability of uKIM-1 after multiple freeze-thaw cycles. KIM-1 levels were evaluated in freshly collected urine samples and after multiple freeze-thaw (FT; n = 5) cycles over 5 days.
