Immunology is specifically the area of biology that deals with the immune system's construction and operation, the physical separation of self and non-self, and the application of antibody-based laboratory methods or immunoassays. The two primary forms of defense are innate and adaptive immune responses, the latter of which is composed of cell-mediated and antibody-mediated responses. The innate immune system serves as the body's initial line of defense against infection. It has some selectivity for microorganisms, activates the acute inflammatory response, and operates quickly but it has no memory. The adaptive immune system, in contrast, takes more time to mature, is extremely specialized, and retains the memory of earlier microbial encounters. Monoclonal antibodies can be used to identify surface molecules on a variety of immune cells and other tissues, which is crucial for the separation, characterization, and classification of immune cells as well as the investigation of the structure and function of diverse membrane surface molecules.

Abeomics offer several immunological antibodies that include both monoclonal and polyclonal antibodies like TIM-3, CD3, CD26, STING, NR2F6, RAGE, and many more.
