B-cells are also another type of WBC.
- It has a receptor protein on is surface that binds complementary antigens.to form an antigen-antibody complex.
- Each B-cell has a different antibody on its surface that only binds specific antigen. When they bind, the B-cells is activated.
- This process is called clonal sectional and B-cell divided into plasma cell.
- Plasma cells are identical to B-cells. They secret loads of (monoclonal) antibodies, specific to that antigen.
- An antibody has two binding sites, so it can bind to two antigens at the same type, clumping them together ( this is called agglutination)
- This make the job for phagocytes easier and more efficient.
