Effects of Different Anticoagulants on Determination of Erythrocyte Glutathione Peroxidase
Effekt av olika antikoagulantia på beståmning av glutathionperoxidas i erytrocyter
Acta Veterinaria Scandinavica volume 22, pages 472–479 (1981)
Abstract
Glutathione peroxidase (GSH-Px) was determined in whole blood from cows, goats and horses using cumenehydroperoxide as substrate. Heparin was found to be the most suitable anticoagulant. The highest activities of GSH-Px were found with high concentrations of heparin in the blood samples (1000 and 1250 IU/ml of blood). Sodium fluoride and especially EDTA and sodium citrate gave lower activities of the enzyme.
Storage of the blood samples at room temperature (~20°C) or in a refrigerator (~5°C) for 3 days resulted in significantly lower activities of the enzyme, especially in horse blood.
Sammanfattning
Glutationperoxidas (GSH-Px) bestämdes i helblod från kor, getter och hästar. Cuminhydroperoxid användes som substrat vid bestämningarna som utfördes i en LKB 8600 Rection Rate Analyzed. Heparin var det mest lämpliga antikoagulantium som testades. De högsta aktiviteterna av enzymet uppmättes då höga halter av heparin fanns i blodprovet (1000 och 1250 ΙΕ/ml blod). Natriumfluorid men specieilt EDTA och natriumcitrat gav lägre enzymaktiviteter vid samtidig bestämning på samma blodprov.
Förvaring av blodp roverna i rumstemperatur (20°C) eller i kylskåp (5°C) under 3 dagar gav signifikant lägre enzymaktiviteter. Detta var specieilt tydligt i hästblod.
