Notizen:
Various techniques for recombining the fully reduced A and H chains of insulin were studied. Best results were obtained from water solutions of the reduced chains allowed to oxidize by standing in air at 3 °C. and from metal-catalyzed oxidation under the same conditions but in 7.6M urea solutions. Average net regeneration of insulin was 6% by weight, based on rat hemidiaphragm analysis for insulin activity. The theoretical yield for a random recombination of the A and B chains was calculated to be 3%. The 50% yield of insulin (from the oxidation of reduced insulin thiosulfate) reported by Jiang et al. could not. be confirmed.
