Antioxidant Activities and Repair Effects on Oxidatively Damaged HK-2 Cells of Tea Polysaccharides with Different Molecular Weights

<div>Changes in mitochondrial membrane potential of damaged HK-2 cells after being repaired by TPSs with different Mw. (a) Dot plot of Δ<i>ψ</i>m detected by flow cytometry. (b) The quantitative results of the red/green fluorescence intensity ratio. NC: normal control; PC: positive control (CCCP); DC: damaged control (oxalate). TPS concentration: 80 <i>μ</i>g/mL; oxalate damage concentration: 2.6 mmol/L. Damaged time: 3.5 h; repaired time: 10 h. Data were expressed as mean ± SD of three independent experiments.
