It is very difficult to analyze some gene expression products, such as isopentenyl transferase (ipt), in transgenic investigation because they are trace in organisms. A convenient method is described to determine trace content gene expression product which is hard to purify. The method includes predicting and synthesizing the antigenic peptide according to the cDNA sequence, coupling the synthetic antigenic peptide with carrier protein, raising specific antibodies against the synthetic antigen, and detecting the gene expression product by ELISA and Western blot.展开更多
