The translationally controlled tumor protein (TCTP) is a multi-functioning protein that performs vital roles,particularly in various complicated life processes.To further understand the biological function of translationally controlled tumor protein (TaTCTP) gene from wheat,total RNA was isolated from wheat leaves and then TaTCTP gene was amplified by PCR after reverse transcription by using the anchored primers oligo(dT)1s.And then TaTCTP gene was connected into PMD19-T vector for sequence.The recombinant expression vector (pET30a-GST-TaTCTP-His) was constructed and transformed into E.coli strain Rosetta (DE3) subsequently,then a proximate 20 kDa protein in Rosetta (DE3) was expressed and characterized by SDS-PAGE.Moreover,TaTCTP fusion protein was purified by Ni-NTA affinity chromatography from recombinant bacterial lysate and was used to immunize rabbit to produce polycional antibody.The titer and specificity of the anti-TaTCTP antibody were successfully detected by indirect ELISA and Western blot analysis.
