5
Q

A
Immunoglobulin M (IgM) Immunoglobulin G (IgG)
6

Define: Immunoglobulin M (IgM)
A
- First antibody produced
- Largest antibody molecule
- Pentomer (contains 5 IgG’s)
- does NOT last long in the host
- Presence indicates current or recent exposure to antigen
7
Q
Define: Immunoglobulin G (IgG)
A
- Follows production of IgM
- Long lasting antibody
- Presence indicates past exposure to antigent
8
