THE MOBILITY OF THE GELATINATE ION
1Chemical Laboratory of the University of Michigan, Ann Arbor.
Abstract:
1. Many measurements were made with the two systems H(2)/NaOH C/NaOH C + x gm. gelatin/H(2) H(2)/NaOH C/KCl (sat.)/NaOH C + x gm. gelatin/H(2) in which x was varied from zero to more than enough for complete combination. 2. From these measurements the change in boundary potential with quantity of gelatin present was determined. 3. The boundary potentials were calculated by means of a modified form of the Henderson equation. 4. The results indicate that the mobility of the gelatinate ion is about 20.

DNA Agarose Gel Electrophoresis
Gel extraction follows five major steps: running gel electrophoresis to separate fragments, isolating the individual bands, extracting DNA from those bands, and removing the dye and salts from the extracted mixture to obtain pure DNA.

SDS-PAGE
A variation of gel electrophoresis, termed polyacrylamide gel electrophoresis (PAGE), is commonly used for separating proteins according to their molecular size by passing them through a polyacrylamide gel. Because of the varying charges associated with amino acid side chains, PAGE can be used to separate intact proteins...
