Final answer:
The production of antibodies in the immune system involves the activation and division of B-cells. Memory B-cells produce antibodies with higher affinity on re-exposure to an antigen. These antibodies are produced at a rate of about 2000 molecules per second.
Step-by-step explanation:
The production of antibodies in the immune system is a complex process involving the activation and division of B-cells. When an antigen is encountered for the second time, memory B-cells produce antibodies with higher affinity due to affinity maturation. These antibodies are produced at a rate of about 2000 molecules per second. In order to produce large quantities of antibodies, hybridoma cells are often grown as intraperitoneal ascitic tumors induced by mineral oil injection.
