One of the primary differences between the three is the type of macromolecule they detect. These three blotting methods have similarities but different in a lot of things. There are different types of blotting procedures but the three common types are a northern blot, southern blot, and western blot. The processes for each are similar, involving gel electrophoresis, transfer to a membrane, and hybridization. (5, 8)Īutoradiograph, Detection of light, and Changes in colorīlotting is a special method used to identify a specific DNA, RNA, and protein from a given sample. Answer While both techniques are used to identify nucleic acid sequences, Northern blotting is performed to detect RNA sequences, while Southern blotting is done to detect DNA sequences. Used as a definite measure for Lyme disease, herpes, hepatitis B, and Creutzfeldt-Jacob disease.It is useful in gene expression studies.Identify the specific RNA sequence in a given sample.To detect a specific DNA sequence in a given sample.It is used in paternity testing.It is used in DNA fingerprinting.It is used for victim identification.It is used for identifying criminals.It is useful in genetic diseases and infectious agents.It is used in mutation and identification of gene rearrangement. George Stark’s group at Stanford University in 1979 James Alwine, David Kemp, and George Stark in 1977 (9)Ī blotting procedure used for identifying a specific amino acid sequence in proteins.

It is an adaptation of the southern blot procedure, which is useful in detecting a specific sequence of DNA through hybridization with complementary DNA. Point of comparisonĪ procedure used to identify a specific sequence of DNA. Image 12: The image shows the basic comparison between southern blot, northern blot, and western blot.

Detecting the presence of HIV antibody in serum.

Detecting the presence of the virus and/or bacteria in the serum.

Identifying the number of protein in a given sample.

Another term for western blot is protein blot or immune-blotting. It consists of different steps such as electrophoresis, transfer, and detection of specific proteins. Western blotting helps to detect a particular amino acid sequence in a mixture of protein. This procedure separates protein according to its size and in a straight column so that researchers can easily compare the amount of protein across various samples that run next to each other. The process is briefly described in the following points: The genomic DNA is digested with a restriction enzyme (one or more) this DNA was isolated from cells/tissues.

Hybridization – It is a phenomenon in which a single-stranded DNA/RNA molecule anneals to complementary DNA/RNA. Key Differences Conclusion Comparison Chart Definition of Southern blotting technique This is the first nucleic acid blotting technique.

Denature – To alter or to take away the natural qualities, to destroy the characteristic properties using heat, acidity, and other measures.

Capillary transfer – The ability of the liquid to flow in a narrow space.

Electrophoresis – A method used in a laboratory setting to separate charged molecules such as DNA with relation to the molecule’s size.

Let us take a look at the differences between the three: Terms commonly used in performing blotting procedures.
