Tanned gelatin: some biophysical and biochemical properties of a new gel exclusion agent and its application to the chromatography of proteins and viruses

Katz, Woolf 07 April 2020 (has links)
The principal aim of this study was to develop a new bed material suitable for gel exclusion chromatography, which would embrace all the desirable characteristics of available materials used for this purpose and if possible improve on some of them. The two most important limitations of existing gel media concern their exclusion limits and rigidity. Agar and agarose have been found satisfactory for the separation of larger molecules including some viruses, but difficulties may arise at low gel concentrations due to the low mechanical strength of the granules. The dextran and polyacrylamide gels have in general a rigidity equal to that of agar and agarose, but cannot be prepared with such large pore sizes and are therefore limited to the separation of smaller molecules.

The chromatographic analysis of the enzyme cellulose

Glennon, William Edward January 1956 (has links)
Thesis (M.A.)--Boston University / This thesis attempted to give further evidence to the multiple component theory of the enzyme cellulase as well as presenting methods of purifying the enzyme. Cellulase was prepared in this laboratory from Myrothecium verrucaria. Batch absorption experiments using cellulose as adsorbent showed that 30% of the activity and protein could be adsorbed at pH 5 with acetate buffer. A very dilute salt concentration as 0.0001 M NaCl allowed 58% adsorption of activity in the batch adsorption experiments with cellulose. The long cellulose chromatographic column adsorbed irreversibly 100% of the activity allowing the protein and carbohydrate to be eluted. The column of cellulose must be permitted more sites for the enzyme to absorb to than just placing the enzyme in the cellulose and mixing. The short cellulose columns showed the presence of a readily absorbed component as well as a less readily absorbed component. [TRUNCATED]
