IN SITU HYBRIDIZATION PROTOCOLS
The first three protocols describe isolation and purification of probe (plasmid) and plant genomic DNA, and the preparation of genomic blocking DNA. Other protocols describe details of chromosome preparation and in situ hybridization . The last protocol describes a modified N-banding technique that can be combined with in situ hybridization for simultaneous chromosome identification and mapping.
Biotin labeling and hybridization of probe to chromosomes
Chromosome preparation for in situ hybridization
