Extreme care should be used to identify and verify positive reactions, however, because cross-reactions are common. Counterstaining is essential for examining worms by immunofluorescence and is used to identify the exact cell in which an antigen appears. Methods for counterstaining include labeling all cells with a fluorescent dye that is specific for nucleic acids (e.g., DAPI or propidium iodide) and using GFP driven by tissue-specific promoters. - [Read Antibody Addition and Detection for Staining Caenorhabditis elegans Protocol]

Category: E Coli Protocols: E coli Protein Protocols

Protocol for the expression of cloned genes in E. coli using IPTG-inducible promoters. Protocol describes how (1) to clone cloned sequences encoding open reading frames in plasmids carrying IPTG-inducible promoters, (2) to optimize expression of target proteins in transformants carrying these recombinants, and (3) to scale-up production of foreign proteins. - [Read Expression of Cloned Genes in E. coli Using IPTG-inducible Promoters Protocol]

In vitro transcription reactions employing T3, T7 or SP6 phage-encoded RNA polymerases are widely used to synthesize RNA from recombinant vectors containing appropriate promoters. Production of large amounts of specific RNA is valuable in the preparation of hybridization probes and in vitro translation studies; in the synthesis of ribozymes, rRNA, SRP, antisense RNA and substrates for RNA splicing; and in RNA-protein interaction studies. - [Read Protocol: Purification of In Vitro Synthesized mRNA with Microcon or Centricon Centrifugal Filters]
