Abstract:
A semi-automated radiometric-microbiological assay (RMA) was developed and applied for the analysis of pantothenic acid in human blood and milk. The RMA is based on the measurement of 14CO2 produced from the metabolism of L-[1-14C]methionine or L-[1-14C]valine by the yeast Kloeckera brevis in the presence of pantothenic acid. The assay was shown to be sensitive and specific for the analysis of this vitamin in biological fluids.
