2019-nCoV Antibody (IgG/IgM)Combined Test Kit

When the human body contacts with foreign antigens, the first antibody produced is IgM, which is secreted directly by the receptor on the surface of B cells. The B cells that produce IgM enter the lymph nodes, receive stimulation from T cells and antigen-presenting cells in the center of occurrence, further mature, differentiate into plasma cells, and produce large amount of IgG.
