Objective To screen and identify the protein from tachyzoite lysates interacting with the C-terminal cytosolic tail domain of microneme protein 8(MIC8CTD)in Toxoplasma gondii. Methods Glutathione Sepharose beads were incubated with GST-MIC8CTD protein and GST protein(as a control protein),respectively,and then incubated with tachyzoite lysates.Bound proteins were eluted using sample buffer.Eluants were resolved using SDS-PAGE and transferred onto polyvinylidene difluoride(PVDF)membranes.Protein bands cut fr...
