DNA Preparation and Needle Loading for Gene Delivery by Microinjection Protocol - http://www.cshprotocols.org/cgi/content/abstract/2006/30/pdb.prot4652

Category: Microinjection Protocols: Microinjection of DNA Protocols

For microinjection into cells, high-quality plasmid DNA is purified using standard procedures. The resulting preparation is then delivered into the microinjection needle by either a back-filling or a forward-filling approach. - [Read DNA Preparation and Needle Loading for Gene Delivery by Microinjection Protocol]

Gene Delivery by Direct Injection (Microinjection) Using a Controlled-Flow System Protocol - http://www.cshprotocols.org/cgi/content/abstract/2006/30/pdb.prot4654

Category: Microinjection Protocols: Microinjection of DNA Protocols

This protocol describes a method for constant-flow microinjection using the Pneumatic PicoPump (World Precision Instruments). This type of system is very simple and can be assembled on a relatively low budget. In this method, a constant flow of sample is delivered from the tip of the pipette, and the amount of sample injected into the cell is determined by how long the pipette remains in the cell. - [Read Gene Delivery by Direct Injection (Microinjection) Using a Controlled-Flow System Protocol]

Gene Delivery to Skin Using Biolistics Protocol - http://www.cshprotocols.org/cgi/content/short/2006/1/pdb.prot4446

Category: Gene Delivery Protocols: Biolistics Protocols

The technique has many advantages—plasmids may be used for delivery, DNA theoretically can be delivered to any cell type, and genes may be delivered to cells in vitro, ex vivo, or in vivo. DNA-coated gold particles are distributed evenly along the length of the tubing, which is subsequently cut into short sections of cartridges to be used in a gene gun. The Helios Gene Gun uses a pulse of helium to launch the DNA-coated particles, spreading them onto the target cells. - [Read Gene Delivery to Skin Using Biolistics Protocol]

Probing Protein Interactions Using GFP and FRET Protocol - http://www.cshprotocols.org/cgi/content/extract/2006/2/pdb.prot3893

Category: Reporter Gene Assays: GFP Assay Protocols

In preparation for FLIM-FRET analysis, the appropriate donor and acceptor components must be introduced into live or fixed cells. The method of introduction depends on the nature of the components and the state of the cells. For example, plasmid DNAs encoding a protein of interest fused to a variant of GFP may be introduced into live cells by transfection or microinjection, whereas labeled antibodies are delivered by microinjection. - [Read Probing Protein Interactions Using GFP and FRET Protocol]
