Immunogenic envelope glycoproteins are produced from enveloped virus, such as of the paramyxoviridae family, particularly PIV-3 and RSV, by culturing the virus in the substantial absence of exogenous serum proteins, isolating the virus from the tissue culture, solubilizing the envelope glycoproteins and isolating the solubilized envelope glycoproteins by chromatography.

Os glycoproteins immunogenic do envelope são produzidos do vírus enveloped, como da família dos paramyxoviridae, particularmente PIV-3 e RSV, cultivando o vírus na ausência substancial de proteínas exogenous do serum, isolando o vírus da cultura do tecido, solubilizing os glycoproteins do envelope e isolando os glycoproteins solubilized do envelope pelo chromatography.
