A method is described for the differential estimation of DNA and RNA from rat liver on filter paper disks. To differentiate between DNA and RNA, samples are subjected to alkaline hydrolysis in microtitration plates prior to absorption on the disks. This procedure eliminates the loss of DNA which is
A new method for purifying arylamine acetyltransferase (AAT) has been devised using polyethylene glycol fractionation and hydroxylapatite chromatography. The new procedure gives a final yield of approximately \(70 \%\) based on activity in crude homogenates and can be performed in a single day. This
The internalization of fluorescent 7-nitro-2,1,3-benzoxadiazol-4-yl (NBD)-phospholipids from the plasma membrane can be assessed by the irreversible quenching of analogues in the outer leaflet by dithionite. Here we have utilized this assay to follow the redistribution of short-chain C6-NBD-sphingom
