What are the 3 types of cells that helper t cells produce upon being alarmed of an antigen?
Helper T cells can produce three types of cells when alerted to an antigen: effector T cells, memory T cells, and regulatory T cells. Effector T cells help eliminate the antigen, memory T cells remember the antigen for future responses, and regulatory T cells help regulate the immune response to prevent excessive inflammation.

What is the effect of not including the antigen or the primary antibody in the ELISA reaction?
