Fluorescence In Situ Hybridization (FISH) is a cornerstone methodology in molecular cytogenetics. By utilizing fluorescently labeled nucleic acid probes that bind specifically to target chromosomal or gene sequences, FISH enables gene localization, copy number analysis, detection of chromosomal structural variations, and identification of pathogenic microorganisms. This technology is widely applied across diverse fields, including tumor diagnosis, genetic disease screening, genomic research, and cell biology studies.

FAQ
1. What gene information is required for probe design?
Provide the target's NCBI ID, genomic coordinates, or FASTA sequence. For non-model species, reference genome data is required.
2. Do you support multiplex FISH probe design?
Yes, we develop multiplex probes (up to 4 colors) with spectral overlap correction.
3. How is probe specificity ensured?
Specificity is guaranteed through:
- Bioinformatics screening to exclude repetitive sequences;
- Post-synthesis validation via Southern blot or qPCR;
- Negative control testing to eliminate nonspecific hybridization.
4. What cell samples are compatible with your FISH probes?
Our probes are validated for cultured cells, tissue sections, blood cells, bone marrow cells, and more. Special sample types should be specified during ordering for customized optimization.
