The antibody recognizes misfolded forms of mutant human SOD1 protein. By native blot, C4F6 is specific for misfolded forms of SOD1 in G93A mutant model, and oxydized SOD1 models compared to normal SOD1. By IF, C4F6 is specific for misfolded SOD1 from G93A mutant model vs. wt SOD1. C4F6 clone is also able to recognize different conformers of misfolded SOD1 under specific conditions detailed in various publications.
