To provide free radical and radiation biology expertise, reagents, technologies, and analysis for individual investigators in the Holden Comprehensive Cancer Center doing basic, pre-clinical, and clinical research.
Provides or advises users on how to perform and analyze experiments, aiding in vector development, enzyme activity assays, cell cycle and thiol analysis, western, northern, and Southern analysis.
Available enzyme assays include: copper-and zinc-containing superoxide dismutase (CuZnSOD), manganese-containing superoxide dismutase (MnSOD), catalase (CAT), glutathione transferases (GSTs), gamma-glutamyl transpeptidase (GGT), gamma-glutamylcysteine synthetase (GCS), and glutathione peroxidases (GPx). Assays for prooxidant production (superoxide, hydrogen peroxide, lipid peroxidation products, etc.) are available.
Antibodies, cDNA probes, and adenoviral vectors coding for primary antioxidant enzymes as well as stably and transiently transfected cells are also provided. The Core aids in transfecting cDNAs into cell lines of interest to investigators, and continues to develop and maintain novel reagents for studies in free radical biology including: antibodies, cDNAs, antisense reagents, and expression vectors for antioxidant proteins including thioredoxin, glutaredoxin, thioredoxin reductases, and thioredoxin peroxidases.
The core provides comprehensive irradiation services (both x-ray and 137Cs) and expertise in redox regulation of the cell cycle and phosphorimaging.
