    Changes of the affinity between fungal proteins and vanillin bonded to thermally modified porous glass support (1984)
    Springer
    Chromatographia 18 (1984), S. 41-43 
    Details
    ISSN: 1612-1112
    Keywords: Affinity chromatography ; Proteins affinity to vanillin ; Controlled porosity glass ; Thermally modified glass support ; Boron enriched glass surface

    Topics: Chemistry and Pharmacology
    Notes: Summary The affinity of peroxidase and the fungal proteins to vanillin attached to controlled porous glasses depends on the porosity of the glass and additional thermal treatment of the support. The additional thermal treatment of controlled porous glasses leads to an enrichment in boron atoms of their surface. The results presented in this paper show a better resolution of the analyzed substances when glass with a surface enriched in boron was used as the support for vanillin.

    Influence of the thermal modification of controlled porosity glass on the affinity chromatography of fungal proteins (1984)
    Springer
    Chromatographia 18 (1984), S. 389-392

    Notes: Summary The properties and the coverage density of chemically bonded phases depend among others on the properties of their supports. Controlled-porosity glasses (CPG) are materials used as a support of bio-active ligands. Their network mainly consist of SiO2 as well as of a small amount of B2O3 and Na2O. The characteristic feature of porous glasses is the possibility of a change in the surface boron concentration leading to the change of the properties of their surface. This paper deals with the results of the separation of fungal proteins on packings consisting of vanillin bonded to CPG with different boron concentration on its surface. It appears from the data obtained that the changes in the affinity of the fungal proteins to the packing are related to the extend of the thermal treatment of the CPG. The protein fractions separated by chromatography were confirmed to be homogeneous by poly-acryloamide gel disc electrophoresis.

    Influence of pentaerythritol triacrylate acrylic carrier swelling on immobilization of enzymes (1995)
    New York, NY [u.a.] : Wiley-Blackwell
    Journal of Applied Polymer Science 58 (1995), S. 1317-1323 
    Details
    ISSN: 0021-8995

    Notes: Suspension copolymerization and modification of pentaerythritol triacrylate (PENTA)-butyl acrylate (BA) matrices with ethylenediamine (EtDA) are discussed. It is shown that aminolysis in water solution offers gel structure carriers with small pore radii (about 3 nm). These carriers are characterized by the high swelling and sharp correlation between the pH value and the specific volume. The enzymes (acylase, glucoamylase, and peroxydase) are immobilized by means of the glutaraldehyde method. The best matrix seems to be copolymers modified in a 95% solution of ethylenediamine in water. Preparations do not lose activity after 1 month storage at 4°C. © 1995 John Wiley & Sons, Inc.
