I am unable to get the protein at soluble fraction from plant but has managed to solubilized in bacteria using tag. Is there any way to find interaction partner of this protein using healthy plant extract and bacteria isolated protein.
For priliminary idetificationof interaction partners you can perform pull-down assay with recombinant protein and plant lysate. The Interacting proteins can be identified by subjecting the eluted sample to 2D gel electrophoresis followed me peptide mass fingerprinting.
