The Isoelectric Point of a Standard Gelatin Preparation1

Two samples of a standard gelatin were studied, both prepared according to published specifications and washed free from diffusible electrolytes. The isoelectric point of this material was determined in four ways. 1. The pH values of solutions of gelatin in water approached the limit 4.86 +/- 0.01 as the concentration of gelatin was increased. 2. The pH values of acetate buffers were unchanged ...

The Isoelectric Point of Gelatin at 40°c

Measurements have been made at 40 degrees C. of the osmotic pressure and viscosity of 1 per cent gelatin solutions containing varying amounts of hydrochloric acid or sodium hydroxide. Each property was found to exhibit a decided minimum near pH 4.7. In the osmotic pressure experiments the pH of the inside solutions was greater than that of the outside solutions at pH values below 4.7, while it ...

The Isoelectric Point of Gelatin and Its Rela- Tion to the Minimum Physical Properties of Gelatin

In a preliminary statement the writer (1) presented the proposition that the minimum physical properties of gelatin (conductivity, osmotic pressure, viscosity, maximum opacity) which are usually thought to define its isoelectric point are propert’ies of pure gelatin, and that pure gelatin is not isoelectric; that pure gelatin from lime-conditioned stock is a weak acid which in an electrical fie...

The Swelling of Isoelectric Gelatin in Water

It has been assumed that gelatin consists of a network of an insoluble material enclosing a solution of a more soluble material. The swelling of gelatin is therefore primarily an osmotic phenomena in that the water tends to diffuse in owing to the osmotic pressure of the soluble material. This osmotic pressure is opposed by the elasticity of the insoluble constituent, and equilibrium results wh...

The Isoelectric Point of Adsorbed Hemo- Globin*

It is well established that various proteins, as gelatin and albumin, can be adsorbed on various adsorbents so that the proteincoated particle of adsorbent behaves electrophoretically as a particle of protein (Loeb, 1923; Freundlich and Abramson, 1928). Dummett and Bowden (1933) have recently reported, however, that the behavior of adsorbed hemoglobin varies with the adsorbent surface. Thus, wh...
