Immunocytochemistry and Immunohistochemistry

Immunocytochemistry 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.

Key Techniques in Microbiology

Aseptic techniques prevent contamination, ensure experimental accuracy, and protect researchers and microbial cultures. These techniques are essential in clinical, industrial, and research settings where sterility is required.Maintaining Sterility in Laboratory PracticesScientists maintain sterility by sterilizing tools with heat or chemicals, disinfecting work surfaces, and handling cultures in controlled environments. Working near an open flame or within a laminar flow hood reduces the risk...

Area of Science:

Immunology
Biochemistry

Background:

The immunoglobulin G (IgG) isotype plays a critical role in the adaptive immune system.
Understanding the functional diversity among IgG subclasses is essential for comprehending immune responses.

Purpose of the Study:

To highlight the foundational discovery of discrete IgG subclasses.
To establish the framework for understanding differential IgG subclass activity.

Main Methods:

Historical review of immunological research.
Analysis of foundational studies on IgG isotype classification.

Main Results:

Identification of distinct subclasses within the IgG isotype.
Established the basis for differential IgG subclass function.

Conclusions:

The discovery of IgG subclasses revolutionized the understanding of immune response mechanisms.
Differential IgG subclass activity is key to both protective immunity and self-reactivity.
