Chromogenic in situ hybridization (CISH) is a technique that combines in situ hybridization with immunohistochemistry to detect specific DNA sequences within tissue samples using brightfield microscopy. CISH uses nucleic acid probes labeled with enzymes that produce colored precipitates when exposed to chromogenic substrates, allowing.

FISH, or the occasional alternate of chromogenic in situ hybridization (CISH), is a cytogenetic technique developed in the 1980s that uses fluorescent probes to interrogate the genome of a cell for the presence, quantity, and distribution of DNA with a high degree of sequence complementarity. Fluorescence microscopy is used to visualize the presence or absence as well as location of where the.


What is in situ hybridization and what are the recent advancements with this indispensable

Introduction. In situ hybridization (ISH) has become an extremely useful tool for the clinical pathology laboratory to aid oncologists, geneticists, and infectious disease specialists in the diagnosis and treatment of their patients. ISH utilizes nucleic acid (DNA or RNA) probes to assess intact cells for various types of genetic alterations.

Chromogenic in-situ hybridization (CISH) is a relatively new method for determination of gene amplification using a peroxidase-based chromogenic reaction, which can be viewed using a conventional bright field microscope. Like FISH, CISH determines the actual degree of HER2 gene amplification. However, unlike FISH, positive signals can be.

Chromogenic in situ hybridization (CISH) is a cytogenetic technique that combines the chromogenic signal detection method of immunohistochemistry (IHC) techniques with in situ hybridization. It was developed around the year 2000 as an alternative to fluorescence in situ hybridization (FISH) for detection of HER-2/neu oncogene amplification. CISH is similar to FISH in that they are both in situ.

3.1. DNA In Situ Hybridization of the Specific Genes. DNA in situ hybridization is used to identify the position of genes and localize and detect the specific DNA sequences in cells. There are many types of ISH laboratory techniques in which a single-stranded DNA probe is complementary paired with target gene.

8. Chromogenic In Situ Hybridization (CISH) CISH enables examination of gene amplification, gene deletion, chromosomal translocations, and chromosomal number. This approach uses conventional peroxidase or alkaline phosphatase reactions using bright-field microscopy on tissues fixed by formalin and embedded in paraffin.

Chromogenic in situ hybridization (CISH) is emerging as a practical, cost-effective, and valid alternative to fluorescent in situ hybridization in testing for gene alteration, especially in centers primarily working with immunohistochemistry (IHC). We assessed Her-2/neu alteration using CISH on formalin-fixed paraffin-embedded primary invasive ductal carcinoma tumors in which IHC (CB11.

The chromogenic in situ hybridization (CISH) technique, on the other hand, is a suitable alternative to FISH. CISH produces a permanent chromosome stain by using peroxidase- or alkaline phosphatase-labeled reporter antibodies that interact with the hybridized DNA probe, which are subsequently detected using an enzymatic reaction [8] .
