title: Erythrocyte transketolase, a new semi-automated method.
abstract: This paper describes a method to determine transketolase activity in erythrocytes, with or without addition of thiamine-pyrophosphate, by quantitating the formation of glucose-6-phosphate forming during the incubation of hemolysed blood with ribose-5-phosphate. Glucose-6-phosphate is determined enzymatically, after deproteinisation of the sample, using a centrifugal fast analyser. The proposed method gave a correlation of r = 0.89 with an accepted colorimetric method. Reference values for blood are in the range 32--101 U/l.
