FEATURE
Three radio-iodinated pork insulin products are designed for in-vitro determination of circulating insulin in free or bound form; have uses in radio immunoassay procedures; all behave like unlabeled insulin in dialysis, chromatography, electrophoresis, and other tests; specific activity in Inusay131 is 35 to 65 millicuries per milligram, in lnusay-131-H 100 to 400 millicuries per milligram Chemicals exhibit even-sidedness, light fastness, and production economy for papermakers Packages made from this transparent, edible material can be produced on standard packaging machines with only slight modifications; film is impermeable to oxygen and nitrogen and good barrier to oil and grease Substance has use in making spirit-carbon (hecto) papers; designed primarily for papers producing a relatively small number of copies; jet black color does not change its shade during runoff Dry chemical powder quickly knocks down fire caused by gasoline and oil; remains fully effective when used with foam Cellulose ether displays improved flow and leveling, color acceptance, and resistance to aqueous phase separation and enzyme degradation; has uses in paper coatings, sizings and backsizings, adhesives, and emulsions; dispersible Silicone-organic product offers good lubricity for almost all metals in sliding or rolling contact, even with high pressures; useful also for paper and textiles; can be removed by most solvents and by vapor degreasing; nontoxic and nonstaining; supplied in quick-drying solvent for spray applications Heat-curing material is designed for clear coatings on paper, board, film, or foil; has excellent adhesion and flexibility and high-gloss color retention under fast-line speed application Nonsoap synthetic hydrocarbon grease combines temperature advantages of synthetic and superior lubrication properties of petroleum lubricants; designed for military and industrial extreme temperature uses; does not deteriorate seals or paint; performs well under high load
