Stockwell’s group conducted an antibody screen to detect ferroptosis in mice immunised with erastin treated membranes from lymphoma cells.100 Interestingly, they identified an antibody (3F3 ferroptotic membrane antibody) with a human transferrin receptor 1 protein antigen that was effective as a ferroptosis staining reagent, leading to the proposal that transferrin receptor is a selective ferroptosis indicator. This evidence concerns the gene TFRC and lymphoma.
