Abstract: An antibody is prepared from a stable new form of nerve growth factor having a molecular weight of about 116,000. The pure nerve growth factor is obtained from an extract of mouse submandibular gland or mouse saliva which is subjected to ion-exchange chromatography to recover a component of the gland or saliva rich in the nerve growth factor and containing proteinaceous material which does not degrade the nerve growth factor. The component rich in nerve growth factor is subjected to at least one additional chromatography step, usually two to four, to obtain pure nerve growth factor. The pure nerve growth factor then is injected into the blood system of an animal to form the antibody which is recovered from the animal's blood serum.

Abstract: In preparing organic sulfides by reacting olefins (e.g., butylenes) with a sulfur halide to form a sulfohalogenated intermediate which is subsequently sulfurized and dehalogenated by reaction with an aqueous solution of an alkali metal sulfide compound to form a noncorrosive organic sulfide product of high sulfur content, the copper strip corrosion activity is improved by resulfurizing the sulfurized olefin by contacting it with additional aqueous metal sulfide in the presence of a lower molecular weight alcohol, such as isopropanol.

Abstract: A material capable of forming hydrogen bonds or covalent bonds with loading materials incorporated in loaded cells is introduced into the cells with the loading materials to inhibit the destruction of the cell membranes by the loading material after the permeability of the membranes is brought back down to its normal value. In order to provide for the hydrogen bond formation with common loading materials, such as methotrexate, proteins such as albumin and sugars such as sucrose are effective. The time period during which these materials inhibit a destructive effect on the membranes of loaded cells is well defined.
