  • Title: Semlike Forest virus membrane proteins. Preparation and characterization of spike complexes soluble in detergent-free medium.
    Author: Helenius A, von Bonsdorff CH.
    Journal: Biochim Biophys Acta; 1976 Jul 15; 436(4):895-9. PubMed ID: 952923.
    Abstract:
    After Triton X-100 delipidation and subsequent Triton X-100 removal in a sucrose gradient the membrane protein spikes of Semliki Forest virus remained soluble in aqueous buffers. It was shown they were present as octameric complexes with a molecular weight of 95-10(4) and that they contain less than 4% lipid and detergent by weight. In electron microscopy after negative staining they appeared as "rosette"-shaped particles. Part of the protein could also be found associated in ordered paracrystalline arrays.
