Transgene Mapping
- Chromosome mapping of cDNA or genomic DNA fragment on banded chromosomes (human, mouse, rat, hamster, chicken, snake, etc.)
- Comparative chromosome mapping between different species
- Detection of chromosomal deletion / amplification in tumor cell lines

Transgene mapping with M-FISH
For transgene mapping or gene mapping analysis on cells with chromosomal abnormalities, we can use the FISH mapping technique with M-FISH to determine chromosomes.
