the injection of tiny amounts of a substance into a cell by using micromanipulation instruments.

microinjection

A method of introducing DNA into a cell by direct injection into the nucleus, using a microcapillary pipette.

microinjection

a method for introducing new DNA into a CELL by injecting it directly into the NUCLEUS or CYTOPLASM using a thin glass needle. The technique has been used to inject cloned genes into the nucleus of an egg cell in vitro, to generate a TRANSGENIC ORGANISM.

microinjection

a method in which very finely drawn glass pipettes held in a finely adjustable mechanical device are used to introduce new materials (antibodies, organelles, DNA) into cells as they are visualized under a microscope.
