SOD1 Pre-formed Fibrils (PFFs) & Monomers
Superoxide dismutase 1 (SOD1) is a copper/zinc-containing enzyme that plays a critical role in cellular antioxidant defense by catalyzing the conversion of superoxide radicals into oxygen and hydrogen peroxide. Present in nearly all mammalian cells, SOD1 helps maintain redox balance and protect against oxidative damage. In Amyotrophic Lateral Sclerosis (ALS), mutations and misfolding of SOD1 lead to the formation of neurotoxic aggregates that contribute to motor neuron degeneration.
StressMarq Biosciences produces SOD1 protein aggregates, including monomeric and fibrillar forms, optimized for ALS research. These reagents support studies on protein misfolding, oxidative stress, and neurotoxicity, enabling the development of disease models and the screening of potential therapeutics. Our SOD1 constructs are validated for activity and reproducibility, helping researchers advance translational research in neurodegeneration.
StressMarq manufactures SOD1 fibrils and monomers for use in neurodegenerative disease research.
- Human Recombinant SOD1 Pre-formed Fibrils (PFFs) | catalog# SPR-470
- Human Recombinant SOD1 Monomers | catalog# SPR-435
StressMarq’s SOD1 fibrils seed the aggregation of SOD1 monomers, demonstrated through increased fluorescence in Thioflavin T assays.
TEM of human SOD1 Pre-formed Fibrils (PFFs) (PFFs)
Thioflavin T assay of SOD1 pre-formed fibrils (PFFs) (SPR-470) combined with SOD1 monomers (SPR-435). Fibrils seed the aggregation of monomers, leading to an increase in Thioflavin T fluorescence.
