| Abstract: | A commercial radioassay kit for folate (Radio-chemical Centre Amersham, England), produced for clinical analysis, has been tested for folacin assay in foodstuffs. The binding capacity of porcine binder was determined for different folates and compounds interfering with the microbiological assay. Recovery of standard addition of N5-methyltetrahydrofolate to the foodstuffs extracts estimated by radioassay varied from 96 to 105%. |
