| pubmed-article:6312248 | pubmed:abstractText | The specific activities of 2',3'-cyclic nucleotide 3'-phosphodiesterase (CNPase, EC3.1.4.37) in erythrocyte membranes from five patients with active multiple sclerosis (MS) and five normals were compared. The CNPase assay used 2',3'-cyclic NADP as the substrate in an enzyme coupled reaction to produce fluorometrically detectable NADPH. The specific activity of CNPase in the MS and normal groups were 19.2 +/- 2.3 and 28.7 +/- 1.8 mumol/h/mg protein, respectively. The difference was significant with p less than 0.006, based on a one-tailed t-test. | lld:pubmed |
