Abstract:
Rabbit hybridomas are gaining wide acceptance as serologic reagents to identify a variety of antigens, including proteins, small peptides, phosphorylated proteins, and polysaccharides. Rabbits make high-affinity IgG antibodies, all of which bind with high affinity to Protein A from Staphylococcus aureus and Protein G from Group G Streptococcus. Consequently, rabbit monoclonal antibodies of desired specificity can be rapidly detected using Protein A/G as secondary reagents. Here we describe the method for generating rabbit monoclonal antibodies using the rabbit hybridoma fusion partner 240E-1. The method begins with the immunization of rabbits and ends with the cloning the antigen-specific hybridomas.

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.

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.
