Optimisation of expression and purification of the feline and primate foamy virus transmembrane envelope proteins using a 96 deep well screen

► Expression and purification of the transmembrane envelope proteins of foamy viruses. ► Screening assay for optimisation of expression in 96 deep well plates. ► Characterisation of purified proteins by gel filtration and circular dichroism. ► Application in immunological assays screening for foamy virus infection.
