An evaluation of a modified erythrocyte transketolase assay for assessing thiamine nutritional adequacy.
Transketolase (TK) activity was assessed by incubating hemolyzed whole blood with ribose-5-phosphate both in the presence (TKsat.) and in the absence (TK) of thiamine pyrophosphate (TPP). The amount of pentoses utilized between 5 and 60 min after the start of the incubation was taken as a measure of the TK activity. The TPP effect was expressed at (TKsat. - TK)/TK x 100. The coefficient of vari...

متن کاملA Microbiological Assay Method for Thiamine
It is generally recognized that the most useful and convenient means of quantitatively determining members of the vitamin B complex involve microbiological methods. Several methods of this type have been proposed for the assay of thiamine but each one in use today possesses certain inherent disadvantages that limit its value. The fermentation method of Schultz, Atkin, and Frey (1,2), based on t...
