Fluorescent in situ hybridization probe design.

The fluorescent probes are nucleic acid labeled with fluorescent groups and can bind to specific dna rna sequences. Fluorescence in situ hybridization fish of genes and mrna is most often based on polynucleotide probes. Fluorescence in situ hybridization fish involves the preparation of two main components. Using spectrally distinct fluorophore labels for each hybridization probe this approach gives you the power to resolve several genetic elements or multiple gene expression patterns through multicolor visual display.

Multiplex fluorescence in situ hybridization fish enables you to assay multiple targets and visualize colocalized signals in a single specimen. Where the insert may contain a specific gene or originate from a specific chromosomal. Fluorescence in situ hybridization fish is a molecular cytogenetic technique that uses fluorescent probes that bind to only those parts of a nucleic acid sequence with a high degree of sequence complementarity it was developed by biomedical researchers in the early 1980s to detect and localize the presence or absence of specific dna sequences on chromosomes. However the well established concepts for oligonucleotide probe design cannot be transferred to polynucleotides.

Due to the high allele diversity of genes a single probe is not sufficient to detect all alleles of a gene. The dna probe and the target dna to which the probe will be hybridized. Curr opin biotechnol.
