Immunohistochemistry or IHC refers to the process of localizing proteins in cells of a tissue section exploiting the principle of antibodies binding specifically to antigens in biological tissues. [1] It takes its name from the roots "immuno," in reference to antibodies used in the procedure, and "histo," meaning tissue (compare to immunocytochemistry). Immunohistochemical staining is widely used in the diagnosis of abnormal cells such as those found in cancerous tumors. Specific molecular markers are characteristic of particular cellular events such as proliferation or cell death (apoptosis). IHC is also widely used in basic research to understand the distribution and localization of biomarkers and differentially expressed proteins in different parts of a biological tissue.

How is counter staining used in the process of immunohistochemistry to enhance the visualization of specific cellular components?
Counterstaining is used in immunohistochemistry to provide contrast and enhance the visualization of specific cellular components. It involves applying a different colored dye to the sample, which binds to different structures than the primary antibody used to detect the target antigen. This helps to distinguish the specific cellular components of interest from the background, making them easier to identify and analyze under a microscope.
What are the methods of biological investigations?
Some methods of biological investigations include microscopy, DNA sequencing, immunohistochemistry, and cell culture techniques. These methods allow researchers to study various aspects of living organisms, such as their structure, function, and interaction with the environment.
What is the purpose of Xylene in immunohistochemistry?
Xylene is an organic solvent which is miscible with alcohol and wax. In histochemistry alcohol is used to dehydrate tissue sections and then this alcohol is further replaced by xylene (being miscible with alcohol) in a process called as clearing. After this DPX is used to mount cover slips on the sections. One more use of xylene is to dissolve wax which is used to make sections of tissues. Hence, we see that xylene is a clearing agent capable of dissolving wax as well as alcohol.
What are the alternative methods to western blot for protein detection and analysis?
Alternative methods to western blot for protein detection and analysis include enzyme-linked immunosorbent assay (ELISA), immunohistochemistry (IHC), mass spectrometry, and protein microarrays. These methods offer different advantages such as higher sensitivity, multiplexing capabilities, and the ability to analyze protein interactions.

Where can you find information on immunohistochemistry?
Immunohistochemistry information may be found in medical books, studies on biochemistry and physiological sciences. Medical schools have articles and resource materials which contain case studies in which immuunohistochemistry has been used to diagnose patients.

Why is immunohistochemistry stain working on the control tissue but not the experimental tissue?
There could be multiple reasons why immunohistochemistry staining may work on control tissue but not on experimental tissue, such as differences in antigen expression, tissue processing methods, or antibody specificity. It's important to carefully review and troubleshoot the staining protocol, as well as consider factors like fixation and processing conditions that may affect the staining outcome. Additionally, confirming the presence of the antigen of interest in the experimental tissue using alternative methods can help identify potential issues with the immunohistochemistry staining.
What is the purpose of ethanol hydration in immunohistochemistry?
Ethanol hydration in immunohistochemistry is used to rehydrate tissue sections that have been dehydrated during the staining process. This step allows for better penetration of antibodies and reagents into the tissue, improving the overall staining quality and specificity.

What is immunohisochemistry?
Immunohistochemistry is a lab technique where a slide is made from a slice of tissue. It is treated with an antibody against the protein of interest that is made to bind to the protien with one end and and have a chemical reaction on the other. The chemical reaction can then be used to make the protein visible under the microscope.
