Abstract
Genetic material encoding p30 and B1 peptides of Toxoplasma gondii has been isolated and characterized. This genetic material allows the production of peptides for use in diagnosis or immunization or can itself be directly used in hybridization assays.

A method of producing a p30 protein of Toxoplasma gondii comprising introducing into a host cell an expression vector comprising a DNA sequence encoding the amino acid sequence set forth in FIG. 2a, and transcriptional control sequences, said DNA sequence and transcriptional control sequences having been functionally inserted into said expression vector, and culturing said transformed host cell under conditions that allow expression of said p30 protein of Toxoplasma gondii.
A method of preparing a p30 fusion protein of Toxoplasma gondii comprising
- (a) introducing into a host cell an expression vector comprising:
- (i) a DNA sequence consisting of nucleotides 582-996 of the DNA sequence set forth in FIG. 2a;
- (ii) a DNA sequence encoding a polypeptide of interest linked to said DNA sequence of (i);
- and
- (iii) transcriptional control sequences, said sequences of (i), (ii) and (iii) having been functionally inserted into said expression vector;
- and
- (b) culturing said transformed host cell under conditions that allow expression of said p30 fusion of Toxoplasma gondii.
An isolated p30 polypeptide of Toxoplasma gondii consisting of the amino acid sequence set forth in FIG. 2a.
A recombinant fusion protein comprising a polypeptide encoded by nucleotides 582-996 of the DNA sequence set forth in FIG. 2a fused to a polypeptide of interest.
