Kidney extracts were lysed in lysis buffer [50 mM Tris-HCl, pH 7.4, 150 mM NaCl, 2 mM EDTA, 2 mM EGTA, 0.2% Triton X-100, 0.3% NP40, 100 μM phenylmethylsulfonyl fluoride, 1 mM dithiothreitol, 100 μM Na3VO4, and 1 mM protease-inhibitor cocktail (Sigma)]. Protein concentration was determined by the BCA method (Pierce). Tissue protein extracts (30 μg/lane) were separated on 8–12% polyacrylamide-SDS gels under reducing conditions. Samples were then transferred onto PVDF membranes (Bio-Rad), blocked in TBS with 0.05% Tween-20 and 5% nonfat dry milk, and then incubated overnight at 4°C with the primary antibodies and subsequently incubated with peroxidase-conjugated IgG (Amersham) and developed by ECL chemiluminescence (GE Healthcare). Autoradiographs were scanned using the GS-800 Calibrated Densitometer (Quantity One, Bio-Rad). Primary antibodies were affinity purified anti-mouse/human/rat Foxp3 (1 : 1000) (e-bioscience: 14-4774), NGAL (1 : 500) (Santa Cruz, sc-18698). The efficacy of protein loading and transfer to membranes was assessed by incubation with mouse anti-GAPDH antibody (1 : 5000) (Chemicon: MAB374).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
