Popis: | Conventional ethanol precipitation of sub-microgram amounts of glycogen leads to low yields (less than 50%). Quantitative recoveries of 90% were attained, however, when the isolation temperature was raised to 50 degrees C and ethanol was replaced by the less polar propan-2-ol. This improvement enabled development of an erythrocyte assay for glycogen which was both sensitive (0.1 microgram glycogen) and required only 1 ml of whole blood. 26 paediatric specimens were analysed and a reference range of values from undetected to 78 micrograms glycogen/g haemoglobin (Hb) was obtained. |
