Whether DNA, RNA or protein is the molecule of interest, microinjection provides a means of studying function within the context of the living cell. Microinjection techniques for plant protoplasts utilize a holding pipette for immobilizing the protoplast while an injection pipette is utilized to inject the macromolecule. The first time a new morpholino is used a dose–response experiment should be carried out to optimize the phenotype-to-toxicity ratio. Further, the exact copy number or number of DNA molecules delivered into each cell can be precisely controlled. Only one cell can be injected at a time, and many injections are required before getting a successful transgene expression. It was almost impossible for him to put out of his mind the -------------.. words which he heard from his clever father-in-law.
