| Abstract: | Summary Interaction of sodium dodecyl sulphate with transfusion gelatin has been studied in low pH range by viscosity measurements. It was found that with the addition of sodium dodecyl sulphate to transfusion gelatin at pH's 2.0, 3.0 and 4.0 viscosity decreases until precipitation sets in. With further addition of sodium dodecyl sulphate precipitate redissolves. The decrease in viscosity is probably due to greater compactness of the protein molecules. The behaviour of isoelectric transfusion gelatin towards sodium dodecyl sulphate has been found to be markedly different.With 3 figures |
