nuclei form

(nu’kle-if-orm). Shaped like a nucleus. muclein (nu’kle-in). | A phosphorized protein, CrsHysNoP;Or, forming the e ential chemic constituent of the nuclei of cells. It is a colorle , amorphous compound, soluble in dilute alkalis, but insoluble in dilute acids. The nucleins consist of nucleic acid and a base which varies with the different varieties of nuclein. The nucleins include cell-nucleins or true nucleins, which split up into protein, orthophosphoric acid, and xanthin; pseudo nucleins, para nucleins, or nucleo-albumins, and nucleic acid. The nuclein of various glands and of blood-serum is sometimes given therapeutically. Dose, 30-45 gr. (2-3 gm.). n.-animal, an animal into whose blood a certain amount of nuclein has been injected. n.-bases, the bases formed by the chemic decomposition of nuclein. yeast-n., a compound, CyoHsoNie O,,(P,0,)3, thought to have germicidal properties.
