Answers
True
Explanation:
Immunoglobulins are called IgM, IgG, IgA, IgD and IgE, respectively. They differ in their biological properties, functional locations and different mechanisms for removing antigens from the body.
IgM is the main immunoglobulin of the primary antigen response, being the first class to rise in the acute phase of immunological processes.
Its secreted form is produced before B-lymphocyte maturation and therefore usually has low affinity for antigens.
