Microinjecting Cells Using a Pulsed-Flow Microinjection System
Cold Spring Harbor Protocols, 2011INTRODUCTIONThe efficient delivery of exogenous DNA to cells for expression and function studies is an essential technique of modern cell biology, and direct delivery of genetic material by microinjection remains a reliable means of transfection. A pulsed-flow microinjection system, such as the Eppendorf InjectMan and FemtoJet systems, permits a high ...

Mosquito Embryo Microinjection
Cold Spring Harbor Protocols, 2023Genetically modified (GM) mosquitoes are an important tool in the fight against mosquito-borne disease, both indirectly through their use in research investigating host–pathogen interaction, mosquito olfaction, and anthropomorphic behavior and in future direct uses for suppression and possibly eradication through sterile insect technique (SIT) and/or ...

Microinjection Methods for Neutrophils
2014The ability to microinject substances into the cytosol of living neutrophils opens the possibility of manipulating the chemistry within the cell and also of monitoring changes using indicators which otherwise cannot be introduced into the cell. However, neutrophils cannot be microinjected by the conventional glass pipette insertion method.

Generation of Chimeras by Microinjection
2009Since the technique of introducing a targeted mutation ('gene targeting') into the mouse genome was published almost 20 years ago (Cell 51:503-512, 1987), the number of mouse mutants (mouse models) is increasing, especially after the advent of the full mouse genomic sequence in 2002 and the human genomic sequences in 2003 that reveals more and more ...

Microinjection of Protein Samples
Cold Spring Harbor Protocols, 2007INTRODUCTIONThis protocol describes a method for microinjecting proteins into the nucleus or cytoplasm of adherent cells. Microinjection equipment can be obtained from a number of suppliers; this protocol has been used with the Narishige IM-200 air pressure regulator and the Leitz micromanipulator.

Plating Cells for Microinjection
Cold Spring Harbor Protocols, 2006INTRODUCTIONThis protocol describes a method for plating cells for microinjection onto etched coverslips. The coverslips for microinjection must be marked so that microinjected cells can be identified at time points after injection. A procedure for etching coverslips is given below; alternatively, pre-etched coverslips can be purchased at slightly ...

Abstract During recent decades, microinjection has developed into an important method used by cell biologists, and there have been several thousand papers published describing applications of this technique. The main advantage of microinjection is that it enables the direct introduction of substances into individual cells or ...

Science, 1966
A technique has been developed for injecting known amounts of liquids into fertilized one-celled mouse eggs by use of a calibrated ocular micrometer superimposed on the terminal regions of the injection pipette. From 128 pronuclear eggs, each injected with 180 or 770 cubic microns of bovine gamma globulin at a concentration of 25 milligrams per ...

Implantation of Microinjected Eggs
2003Microinjected eggs are normally incubated overnight in Ml6 microdrop culture at 37°C in CO₂ until 1400 h. By this time the eggs will have developed as far as the two-cell stage. The eggs are then implanted into surrogate mothers. As the membrane covering the oviduct of the rat is much tougher than the mouse, we normally cut it with a very fine pair of ...
