CGH provides a comprehensive picture of all chromosomal gains and losses within a single experiment. In contrast to banding analysis, CGH requires no preparation of metaphase chromosomes from the cells to be analyzed (which in certain tumor types may be difficult or even impossible). - [Read Detection of Chromosomal Imbalances Using DOP-PCR and Comparative Genomic Hybridization (CGH)]

Category: Cytogenetics Protocols: In Situ Hybridization Protocols

This protocol fixes and prepares embryos for in situ hybridization to visualize transcript expression patterns. It is a modification of the method developed by Tautz and Pfeifle for whole-mount in situ analysis of embryos. Use of the standard hybridization protocol on RNAi-treated embryos results in high background staining, which makes visualization of transcript expression patterns practically impossible. The following modifications eliminate this problem and allow visualization of transcript. - [Read Transcript In Situ Hybridization of Whole-Mount Embryos for Phenotype Analysis of RNAi-Treated]
