The Ii antigen system is a human blood group system based upon a gene on chromosome 6 and consisting of the I antigen and the i antigen. [1] The I antigen is normally present on the cell membrane of red blood cells in all adults, while the i antigen is present in fetuses and newborns. [2]
Blood is generally drawn from the father to help determine fetal antigen status. [15] If he is homozygous for the antigen, there is a 100% chance of all offspring in the pairing to be positive for the antigen and at risk for HDN. If he is heterozygous, there is a 50% chance of offspring to be positive for the antigen. [16]
The name rhesus factor (Rh) goes back to the use of erythrocytes extracted from the blood of rhesus monkeys for obtaining the first blood serum.. The Rh blood group system is a human blood group system.
An illustration that shows how antigens induce the immune system response by interacting with an antibody that matches the molecular structure of an antigen. In immunology, an antigen (Ag) is a molecule, moiety, foreign particulate matter, or an allergen, such as pollen, that can bind to a specific antibody or T-cell receptor. [1]
The chemical composition and pH value of the buffer solution also contribute to the effectiveness of heat-induced antigen retrieval. [1] Thus, the AR-immunohistochemistry protocol must be optimized for each tissue type, fixation method, and antigen using a "test battery" to maximize antigen recovery in formalin fixed paraffin embedded sections.

An epitope, also known as antigenic determinant, is the part of an antigen that is recognized by the immune system, specifically by antibodies, B cells, or T cells.The part of an antibody that binds to the epitope is called a paratope.
The p24 capsid protein is the most abundant HIV protein with each virus containing approximately 1,500 to 3,000 p24 molecules. [1] It is the major structural protein within the capsid , and it is involved in maintaining the structural integrity of the virus and facilitating various stages of the viral life cycle, including viral entry into host ...
