NEW ANTIGEN PROTEIN, ITS GENE, RECOMBINANT BACULOVIRUS AND ITS USE

摘要

PURPOSE:To obtain the subject new protein derived from Mycoplasma galllsepticum, usable as a component vaccine for preventing infection of birds with mycoplasma, by integrating a gene derived from Mycoplasma gallisepticum into baculovirus, manifesting. CONSTITUTION:A new antigen protein is capable of being reacted with immune serum of Mycoplasma gallisepticum or infection serum of Mycoplasma gallisepticum, shows pure antigenicity, has a restriction enzyme cleavage map of the formula (ATG is initiation codon; TAA is termination codon; Xb is XbaI; He is HincIII; Sc is ScaI; V is EcoRV; Pv is PvuII; Ps is PstI; G is BgtII; Sp is SpeI; Ss is SsrI; Dr is DraI), shows antigenicity of about 32 kilodalton molecular weight encoded by a DNA derived from Mycoplasma gallisepticum and is usable as a component vaccine for preventing infection of birds with mycoplasma, by integrating a gene derived from Mycoplasma gallisepticum into baculovirus, manifesting.
