Double-stranded RNA (dsRNA) can be efficiently introduced into Caenorhabditis elegans by microinjection into the gonad, the gut, or the body fluid. The RNAi effect will spread within the nematode, exerting an effect beyond the site of injection. - [Read Introduction of Double-Stranded RNA in C. elegans by Injection Protocol]

Double-stranded RNA (dsRNA) can be introduced into Caenorhabditis elegans by soaking the animals in a solution of dsRNA. Alternative methods are dsRNA injection (see Introduction of Double-stranded RNA in C. elegans by Injection) and feeding the animals with bacteria that produce dsRNA. - [Read Introduction of Double-Stranded RNA in C. elegans by Soaking Protocol]

Category: Microscopy Protocols: Live-Cell Imaging Protocols

This protocol describes a method for observing and measuring the movement of RNA molecules in the nucleus of living mammalian cells. Caged fluorescein-labeled DNA oligonucleotides are introduced into living mammalian cells, where they demonstrably hybridize to complementary RNA. After site-specific photoactivation at desired sites within the cell, the RNA movements away from those sites are followed and digitally recorded using a rapid acquisition microscopy system. - [Read Photoactivation-Based Labeling and In Vivo Tracking of RNA Molecules in the Nucleus]

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]

Describes how components (usually Fab fragments of antibodies) that are to be introduced into cells are labeled with fluorescent sulfoindocyanine dyes. - [Read Probing Protein Interactions Using GFP and FRET.]

Category: Transfection Protocols: Electroporation Sonoporation Protocols

Electrocompetent bacteria are prepared by growing cultures to mid-log phase, washing the bacteria extensively at low temperature, and then resuspending them in a solution of low ionic strength containing glycerol. DNA is introduced during exposure of the bacteria to a short high-voltage electrical discharge.

Category: Drosophila Protocols: Drosophila Genetics Protocols

Protocol describes the general procedure for creating mutations in the DNA of Drosophila by exposure to X-rays. Irradiation of cells with X-rays creates double strand breaks (DSBs) in DNA. Mutations introduced in the DNA of germ line cells (sperm) are propagated by mating the exposed males to virgin females. The progeny of this cross can be mated to each other so that a percentage of the subsequent offspring will have two copies of the same mutant allele. - [Read X-Ray Mutagenesis of Drosophila Protocol]
