The cosuppression effect in C. elegans does not spread throughout the animal. Cosuppression in C. elegans can be triggered by highly repetitive transgenes that contain gene constructs. - [Read Cosuppression in C. elegans Protocol]
Cosuppression is a process in Caenorhabditis elegans that closely resembles RNAi. In contrast to RNAi, however, the cosuppression effect in C. elegans does not spread throughout the animal. Cosuppression in C. elegans can be triggered by highly repetitive transgenes that contain gene constructs. - [Read Cosuppression in C. elegans Protocol]

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]

An ideal method of tissue preparation ensures both good specimen morphology and that the target molecules are in the optimum state for probe access and hybridization. DNA:DNA in situ hybridization is usually carried out on chromosome spread preparations where chromosome and nuclei are released from cells and spread on a glass microscope slide. This method yields well separated and enlarged chromosomes with good morphology which can be analyzed in transmitted light or fluorescence microscopes. - [Read Preparation of Chromosome Spreads]
A protocol for the selection of Phage Antibodies using Immobilized Antigen. This method describes the selection of antibodies from bacteriophage antibody libraries that recognize a specific antigen. The phage display library of antibody-displaying phage particles is exposed to antigen attached to a solid substrate (Nunc Immuno™ tubes). The phage particles with affinity for antigen bind to the immobilized antigen and are selected from the library of phage expressing antibodies.
This protocol a protocol on how to generate transfected embryonic stem (ES) cell clones. The previous protocol in this series is the Protocol for Electroporation of ES cells. The next protocol in the series is the Protocol on Disaggregation, Expansion, and Freezing of Transfected ES Clones.
