Abstract
To isolate individual organized constituents from animal or vegetable tissues or organs, e.g. in preparing active fractions from glands having internal secretion for example the thyroid gland and the pancreas, the tissues &c. are dried in a frozen state and powdered after which the coarser parts may, if desired, be separated from the finer parts, the desired constituent being finally isolated by treating successively with liquids of different specific gravity. The tissues may be frozen by means of the usual cooling media e.g. solid carbon dioxide and ether, or liquid air and the separating liquids may be chloroform containing for example 25, 20, 15, 10, and 5 per cent of ether and pure chloroform, a finer fractionation being carried out on the suspension containing the desired constituent. Examples are given of the isolation of muscle nuclei from beef and of colloid from the thyroid glands of pigs, the glands being frozen, dried in a sulphuric acid dessicator, treated to remove as far as possible the fat and connective tissue, ground and sifted and subjected to a double sedimentation in ether, the colloid being finally separated from the second sediment by centrifuging successively with mixtures of chloroform and ether.ALSO:To isolate individual organized constituents from animal or vegetable tissues or organs, e.g. in preparing active fractions from glands having internal secretion for example the thyroid gland and the pancreas, the tissues &c. are dried in a frozen state and powdered after which the coarser parts may if desired be separated from the finer parts, the desired constituent being finally isolated by treating successively with liquids of different specific gravity.
