The ischemic penumbra of rat brain tissues (n = 6) was collected for Western blot analysis as previously described (Liu et al., 2020 (link)). The following primary antibodies were used: anti‐beta‐Actin (Abcam, ab8226, 1:1000), anti‐GPX4 (Abcam, ab252833, 1:1000), anti‐FTH1 (Abcam, ab183781, 1:1000), anti‐TF (Abcam, ab82411, 1:1000), anti‐TF receptor (Abcam, ab269513, 1:1000), anti‐HO1 (Abcam, ab68477, 1:1000), anti‐ACSL‐4 (Abcam, ab155282, 1:1000), and anti‐xCT (Invitrogen, PA1‐16893, 1:1000).
