Abstract:
Antiserum to a protein fraction of an extract of mature styles of P. avium cv. Lambert (S 3 S 4) was raised in rabbits. Two major antigenic components of the style extracts were detected by immunoelectrophoresis and immunodiffusion. The presence of one antigen (S-antigen) correlated with a particular S-genotype (S 3 S 4). This antigen is restricted to mature styles of P. avium. The second antigen (P-antigen) was detected in styles of all Prunus species examined, but not in styles of other species of the Rosaceae. The S-antigen is positively charged and the P-antigen negatively charged at pH 8.8.

Antigen Presenting Cells
T cells require the help of antigen-presenting cells (APCs), which process foreign antigens into smaller fragments that can be recognized by T cells. These APCs are highly specialized cells that efficiently internalize antigens...
Diversity of Antigen Receptors
Before encountering any antigen, lymphocytes express these receptors. On B cells, the antigen receptor is a membrane-bound antibody molecule called BCR; on T cells, it is a T cell receptor or TCR. B and T cell receptors are composed of two...

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.
