In situ hybridization (ISH) allows precise gene expression analysis in cells. Advanced methods like in situ PCR significantly enhance sensitivity for detecting nucleic acids in tissues.

Area of Science:

  • Molecular Biology
  • Genetics
  • Pathology

Background:

  • In situ hybridization (ISH) is a technique for localizing nucleic acids (RNA and DNA) within cells or tissues.
  • It combines molecular biology with histological and cytological analysis for gene expression studies.
  • ISH is a valuable research tool and is increasingly used in diagnostic pathology and microbiology.

Purpose of the Study:

  • To review the applications and recent developments of in situ hybridization (ISH).
  • To highlight the advancements in in situ polymerase chain reaction (PCR) and in situ reverse transcription (RT)-PCR.
  • To emphasize the potential of these enhanced techniques in detecting nucleic acids.

Main Methods:

  • In situ hybridization (ISH) for direct localization of RNA and DNA.
