    Snippet: WWIHS is an experimentally determined algorithm that can be used to estimate the propensity of amino acid sequences to interact with lipid membrane interfaces [49] . Sequences of HCMV gB with positive WWIHS score were identified using Membrane Protein explorer (MpeX version 3.0) (http://blanco.biomol.uci.edu/mpex), a computer program based on WWIHS.

    Document: WWIHS is an experimentally determined algorithm that can be used to estimate the propensity of amino acid sequences to interact with lipid membrane interfaces [49] . Sequences of HCMV gB with positive WWIHS score were identified using Membrane Protein explorer (MpeX version 3.0) (http://blanco.biomol.uci.edu/mpex), a computer program based on WWIHS. HCMV gB synthetic peptides were synthesized by solid phase conventional N-α-9-fluorenylmethyloxycarbonyl chemistry by Genemed Synthesis Inc. (San Francisco, CA). Peptides were purified by reverse-phase high performance liquid chromatography and confirmed by amino acid analysis and electrospray mass spectrometry. Peptide stock solutions were prepared in 10% dimethyl sulfoxide (DMSO, spectroscopy grade): 90% (v/v) H 2 O. Peptide concentrations were determined by absorbance of aromatic side chains at 280 nm (Smart-Spec ™ 3000, BioRad, Hercules, CA).
