In situ hybridization (ISH) is a powerful technique for localizing specific nucleic acid targets within fixed tissues and cells, allowing you to obtain temporal and spatial information about gene expression and genetic loci. While the basic workflow of ISH is similar to that of blot hybridizations—the nucleic acid probe is synthesized, labeled, purified, and annealed with the specific target ...

PGS | CGH | Comparative Genomic Hybridization | IVF1

In the early 1990s, a method known as comparative genomic hybridization (CGH) was developed for the evaluation of chromosomal number in tumors. In 1996, this method was developed and applied to embryos for the first time. CGH allows for the evaluation of every chromosome in a cell. This has been termed comprehensive chromosome screening and it ...

DNA surface hybridization regimes | PNAS

 · Surface hybridization reactions, in which sequence-specific recognition occurs between immobilized and solution nucleic acids, are routinely carried out to quantify and interpret genomic information. Although hybridization is fairly well understood in bulk solution, the greater complexity of an interfacial environment presents new challenges to a fundamental understanding, and hence ...

Top 5 Screening Strategies of Gene Libraries

2. Screening by Colony Hybridization: The DNA sequence in the transformed colonies can be detected by hybridization with radioactive DNA probes (sometimes labeled RNA probes can also be used). Colony hybridization technique is also referred to as replica plating by some authors. The technique depicted in Fig. 9.7 is briefly described.
