[Analysis of the cobalamin coenzymes in mouse splenic tumor cells]
Abstract:
Coabalamine coenzymes were studied in tumor spleen cells of mice with La leukosis. Endogenous cobalamines in the cell extracts were separated by two-dimensional thin-layer chromatography and by bioautography. Analysis of the cobalamines ratio was carried out using bioautochromatographic technique. 5-deoxyladenosyl- and methyl cobalamines were found in extracts of the tumor cells.
