Representative image of a 2% high resolution agarose gel with T. gondii uncut, positive, 183 bp PCR fragments (Lane 2 and Lane 4) and subject to restriction enzyme digestion with the endonuclease EcoRV (Lane 1 and Lane 3). A ready-to-use DNA marker (Lanes M) suitable for sizing linear double-stranded DNA fragments from 25–700 bp was used to confirm the expected digested fragments of 74 bp and 109 bp
