Anti-actin antibodies of human and rabbit origin
Abstract:
The production of actin antisera in rabbits was described and their reaction in various immunological tests were compared with the results obtained with human anti-actin sera (smooth muscle antibodies). Even if the sera may react with different antigenic determinants of actin as suggested by results in immunoprecipitation and blocking experiments, the rabbit and human sera can be used for studies of cells with equal or similar results. A prerequisite was that the rabbit anti-actin titres were high. The difficulty in obtaining strong anti-actin sera in rabbits was confirmed.

Antibody Structure
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.

Introduction to Actin
Antibody Structure and Classes
The basic structure of an antibody consists of four protein chains: two identical heavy chains and two identical light chains. These chains are held together by disulfide bonds and other non-covalent interactions, forming a Y-shaped structure.
