“…Immunohistochemical staining of kidney sections was conducted according to our previous study . The kidney sections were incubated overnight at 4 °C with antibodies against anti-KIM-1 (1:100, ab47635, Abcam), anti-NRF2 (1:200, 16396–1-AP, Proteintech), anti-Keap-1 (1:200, 10503–2-AP, Proteintech), anti-CAT (1:250, 21260–1-AP, Proteintech), anti-SOD (1:300, 10269–1-AP, Proteintech), anti-CD44 (1:500, 15675–1-AP, Proteintech), anti-OPN (1:250, 22952–1-AP, Proteintech), anti-IL-6 (1:200, A0286, Abclonal), and anti-MCP-1 (1:300, ab7202, Abcam).…”
