Guinea pig 7S immunoglobulins (
1 and
2) consist of two groups of molecules (K and L) bearing different types of L chains (
and
). Approximately one-third of the molecules in normal guinea pig
2-globulin bear the
- type of L chains, and all or most of the others bear
-chains.
- and
-chains have similar molecular weights.
