Summary
Protein blotting, or immunoblotting, identifies protein antigens using antibodies. This technique immobilizes proteins from gels to solid phases, proving useful in basic and clinical research, particularly immunohematology.
Area of Science:
- Biochemistry and Molecular Biology
- Immunology
- Clinical Research
Background:
- Protein blotting is a fundamental technique for transferring and immobilizing protein patterns from gel electrophoresis to a solid support.
- This method allows for the specific detection of proteins using antibodies, making it valuable for analyzing complex biological samples.
Purpose of the Study:
- To discuss the features and recent improvements of protein blotting (immunoblotting) techniques.
- To highlight the utility of immunoblotting in basic research and advocate for its expanded use in clinical research.
- To summarize specific applications of immunoblotting within the field of immunohematology.
Main Methods:
- Protein separation using gel electrophoresis.
- Transfer of separated proteins to a solid phase membrane (blotting).
- Detection of specific proteins using antibodies (immunoblotting).
Main Results:

01:20Immunoprecipitation
Immunoprecipitation, or IP, is a widely used technique that employs protein-antibody interactions to isolate proteins or protein complexes in their native state for studying protein-protein interactions, quaternary structures, or supramolecular complexes. Various modifications of the technique, including chromatin IP, cross-linking IP, and fluorescence IP, are commonly used.

01:15Western Blotting
Western blotting is an analytical technique for protein identification. It has various applications in immunology and medicine, including detecting diseases like bovine spongiform encephalopathy, mad cow disease, and human and feline immunodeficiency virus from biological samples.
The technique begins with separating proteins from the sample using sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), followed by protein transfer, immunoblotting, and finally, protein detection.

01:33Enzyme-Linked Immunosorbent Assay
In 1971, Peter Perlman and Eva Engvall developed an Enzyme-linked immunosorbent assay (ELISA or EIA). ELISA differs from western blot in that the assays are conducted in microtiter plates or in vivo rather than on an absorbent membrane.
There are many different types of ELISAs, but they all involve an antibody molecule whose constant region binds an enzyme, leaving the variable region free to bind its specific antigen. Enzyme-substrate reaction allows the antigen to be visualized or quantified.

01:22Immunocytochemistry and Immunohistochemistry
Immunocytochemistry (ICC) and immunohistochemistry (IHC) are techniques that use antibodies to check for specific proteins or antigens in a sample. The technique was first published by Albert Coons in 1941 to detect the presence of pneumococcal antigen in tissue sections from mice infected with Pneumococcus. Immunocytochemistry helps localization of proteins or antigens in individual cells like blood cells, stem cells, etc., while immunohistochemistry does the same for tissue samples.

01:20Immunogold Electron Microscopy
Immunoelectron microscopy utilizes immunogold labeling of endogenous proteins with specific antibodies to detect and localize these proteins in cells and tissues. The procedure provides insights into the distribution and quantification of protein under different stimulation conditions offering clues about their functions. Conjugating highly electron-dense gold particles with primary or secondary antibodies allow antigen detection on and within cells, with high resolution and specificity.
