Evaluation of a direct spectrophotometric method for the rapid determination of ascorbate and dehydroascorbate in blood using ascorbate oxidase

, : Evaluation of a direct spectrophotometric method for the rapid determination of ascorbate and dehydroascorbate in blood using ascorbate oxidase. Biological Chemistry Hoppe-Seyler 367(10): 1047-1054

The application of a technique for the direct spectrophotometric determination of ascorbate and dehydroascorbate in blood samples is described. The reliability of the test system and various disturbing factors are assessed. It is concluded that the technique possesses a high specificity and that interferences by various biochemicals and metabolic intermediates are low. The lowest ascorbate concentration detectable in plasma by this assay is estimated to be about 1 .mu.mol/l.

The role of nutritional factors on heme synthesis and their influence on the development of anemia in the bone marrow during lead exposure is unclear. Previous reports suggested that pteridines could regulate the formation of uroporphyrinogen, a s...

The triggering receptor expressed on myeloid cells (TREM) family of single extracellular immunoglobulin receptors includes both activating and inhibitory isoforms whose ligands are unknown. TREM-1 activation amplifies the Toll-like receptor initia...

I will suggest that the English word 'anger' and its counterparts in diverse languages of the world are based on concepts of anger that have a great deal of complexity. This conceptual complexity derives from several sources: (1) the met...

Twenty- four transgenic founders were generated in which Cre recombinase was placed under the regulation of a 2.5-kb fragment of the human NPHS2 promoter. P...
