Antigen-antibody complex:Img 1

1.	Antigen-antibody complex:Img 1
Answer» 1. Between antigen and antibody there is specificity. 2. Each antibody is specific for a particular antigen. 3. On the antigens there are combining sites which are called antigenic determinants or epitopes. 4. Epitopes react with the corresponding antigen binding sites of antibodies which are called paratopes. 5. The antigen binding sites are located on the variable regions of the antibody. Variable regions have small variations which make each antibody highly specific for a particular antigen. 6. Owing to variable region the antibody can recognize the specific antigen. 7. Antibody thus binds to specific antigen in a lock and key manner, forming an antigen- antibody complex.
