This 5th quantity of analysis tools in Neurochemistry represents a milestone in that it marks nearly a decade because the inception of the sequence. Over those ten years there was a virtually exponential development in neuro­ chemistry followed by way of a number of technical advancements. this can be the justification for our sequence; necessarily we have now purely been in a position to conceal a frac­ tion of the methodological thoughts of the decade, yet now we have attempted up to attainable to create a stability among the various methods and philosophies within the research of the chemical foundation of mind functionality.

G . D. BIRNIE Buoyant Density-Gradient Centrifugation Although high-molecular-weight chromatin can be sedimented to its isopycnic point quite satisfactorily and rapidly in preformed 20-60% (w/v) metrizamide gradients, this method is not generally suitable for sheared chromatin because of the very long time of centrifugation required to ensure that the equilibrium positions have been reached by all species of particles. Moreover, the amount of chromatin which can be fractionated on a preformed gradient is limited.

Digestion of nuclei was carried out on suspensions of 3. 25Msucrose and resuspended in the same buffer at a DNA concentration of 500 pg/ml. The kinetics of DNA digestion following the addition of nuclease were assayed by measuring the amount of A 260 absorbing material soluble in 1 M NaC1-1 M HC10,. RNA contributed less than 5% of the total A,,, of purified nuclei as determined either by alkali digestion or treatment with pancreatic ribonuclease. Nuclease reactions were terminated by the addition of NaEDTA to 5 mM.
