  • Title: Isolation of glycoprotein D from herpes simplex virus type 1 by gel filtration high performance liquid chromatography.
    Author: McGarry TJ, al-Ahdal MN.
    Journal: Biomed Chromatogr; 1989 Sep; 3(5):221-5. PubMed ID: 2553170.
    Abstract:
    Rabbit kidney (RK-13) and human jejunum and ileum (I-407) cells infected with herpes simplex virus type 1, strain F, were radiolabelled with [14C]glucosamine or [35S]methionine for 24 h. The cells were extracted with 1% Triton X-100 and the extracts were separated by gel filtration high performance liquid chromatography. Monoclonal antibody immunoprecipitation of the fractions collected from the column revealed a monomeric glycoprotein D (gD) of 52 - 56,000 molecular weight from RK-13 cells and two monomeric forms of gD, 54,000 and 58,000 molecular weight, from I-407 cells. Densitometry scanning of the autoradiograms from SDS-PAGE showed gD from the RK-13 host cells to be 98.7% pure with the [35S]methionine label and 97.0% pure with the [14C]glucosamine. On the other hand, gD from the I-407 host cells was only 78.6% with the [35S]methionine label and 96% pure with the [14C]glucosamine. This method could provide a means for the isolation of native gD for structural and immunological studies.
