In Situ Hybridization (ISH) Experiment Service
First Edition (Revised on April, 2016)
ISH (in situ hybridization) is based on the principles of complementary base pairing which are appeared in the process of denaturation and renaturation of RNA and DNA. The marked DNA or RNA probes are combined with DNA or RNA in cells, so the DNA-DNA complex, RNA-DNA complex and RNA-RNA complex are formed. ISH is a detection method which is used for analysis of nucleic acid by amplification and collection of probe signal. In the experimental process, special labeled probes can be used to detect the position, content and distribution of nucleic acids, such as the content and distribution of RNA, distribution, position and copy number of chromosome abnormal gene and deletion or insertion of DNA fragments.
