28869736-5	2017	GST tag was cleaved with thrombin, and a crude SOD2 recombinant protein (25 kDa) was obtained and further purified by heparin affinity chromatography.	Heparin	118-125	superoxide dismutase 2	Homo sapiens	47-51	
19016244-6	2008	Analyses of associations between SOD genotypes and levels of plasma SOD activity demonstrated that SOD2 Ala16Val, a dimorphism leading to substitution in the mitochondrial targeting sequence of SOD2, significantly influences plasma SOD2 activity, and that SOD3 Arg231Gly, leading to substitution in the heparin-binding domain of SOD3, significantly influences plasma total SOD activity.	Heparin	303-310	superoxide dismutase 2	Homo sapiens	99-103
