title: Host antigens associated with haemagglutinin.
abstract: A delayed-type hypersensitivity (DTH) test has been used to detect the presence of host-specific antigen(s) is highly purified egg-grown influenza virus, virus components and isolated haemagglutinin. Cyclophosphamide-treated mice, primed with an extract from allantoic fluid, showed DTH reactions when challenged with preparations containing envelope lipid or polymer-type subunits, whereas lipid-free derivatives such as internal virus protein complexes and monomer haemagglutinin preparations lacked the activity. This approach has been extended to demonstrate the presence of associated host antigens in SV40-vector expressed haemagglutinin produced in simian cells.
