IgM
Which antibody arrives after IgM but stays at the site longer?
IgG

Cell type involved in humoral immune response
B cells that transform into plasma cells after antigen stimulation
which type of white blood cell is incapable of phagocytosis
Lymphocytes
what type of cells are memory cells
T cells
B cells
