Immunohistochemistry, using the basic principles of immunology - the antigen-antibody reaction, namely antigen and antibody specific binding principle, by chemical reaction of the labeled antibody reagent (luciferase, an enzyme, metal ions, isotopes) to confirm the antigens (peptides and proteins) in tissues, its location, qualitative and quantitative research, called immunohistochemistry (immunohistochemistry) or immunocytochemistry techniques (immunocytochemistry).It combined the specific of immune response with visibility of histochemistry by means of a microscope (including fluorescence microscopy, electron microscopy) imaging and amplification, detection of various antigens in a cell, subcellular level, such as proteins, polypeptides, enzymes, hormones, pathogens, and receptors. Immunohistochemical techniques have developed rapidly in recent years. It was limited to immunofluorescence techniques in 1950s, but gradually developed after the 1950s to establish a highly sensitive and more practical immunization enzyme technology.
Thymus, a lymphoid organ in humans, is located behind your sternum and between your lungs. The organ is called thymus because its shape resembles that of a thyme leaf. The thymus is only active until puberty. After puberty, the thymus starts to slowly shrink and become replaced by fat. Thymus gland does not function throughout the life, but it has a great responsibility when it's effectively help the body protect itself against autoimmunity, which occurs when the immune system turns against itself. Thus, the thymus plays a vital role in the lymphatic system (your body's defense network) and the endocrine system. A variety of target molecules expressed on thymus tissue is used for the clinical diagnosis of thymus disease, thymus tissue is commonly used in immunohistochemical detection. IHC is an important means to be widely used to detect thymus disease.
Different species of thymus slices as follows:
