Western Blotting
Western Blotting is a laboratory technique used to detect specific proteins in a sample of tissue or cell extract. It is a type of gel electrophoresis that separates protein molecules by size and shape. After the proteins are separated, they are transferred from the gel to a membrane, where they are probed with a specific antibody to detect the target protein.



  • Western Blotting is used to detect proteins that have been separated by gel electrophoresis.

  • It is commonly used in research to study protein expression, protein-protein interactions, and protein modifications.

  • Western Blotting can be used to diagnose diseases and monitor treatment progress.

  • The technique involves several steps, including protein extraction, gel electrophoresis, transfer to a membrane, blocking, antibody incubation, and detection.

  • Western Blotting is a widely used technique in molecular biology, biochemistry, and medicine.



Southern Blotting
Southern Blotting is a laboratory technique used to detect specific DNA sequences in a sample of DNA. It is a type of gel electrophoresis that separates DNA fragments by size. After the DNA fragments are separated, they are transferred from the gel to a membrane, where they are probed with a specific DNA probe to detect the target sequence.



  • Southern Blotting is used to detect specific DNA sequences in a sample of DNA.

  • It is commonly used in research to study gene expression, gene mutations, and genetic diseases.

  • The technique involves several steps, including DNA extraction, gel electrophoresis, transfer to a membrane, blocking, DNA probe hybridization, and detection.

  • Southern Blotting is a widely used technique in molecular biology and genetics.



Northern Blotting
Northern Blotting is a laboratory technique used to detect specific RNA sequences in a sample of RNA. It is a type of gel electrophoresis that separates RNA molecules by size. After the RNA molecules are separated, they are transferred from the gel to a membrane, where they are probed with a specific RNA probe to detect the target sequence.



  • Northern Blotting is used to detect specific RNA sequences in a sample of RNA.

  • It is commonly used in research to study gene expression, RNA processing, and RNA modifications.

  • The technique involves several steps, including RNA extraction, gel electrophoresis, transfer to a membrane, blocking, RNA probe hybridization, and detection.

  • Northern Blotting is a widely used technique in molecular biology and genetics.
