See my chapter in Wier's Handbook of Experimental Immunology; the 5th
edition just appeared, but this information has not changed since the
4th edition. It shows ranges of "normal" values for the different rat
Ig isotypes together with half-lives and other biological properties,
and probably more citations than you want to read. The nominal serum
levels (mg/mg) are shown below:
IgM 0.2-1
IgG1 0.5-6
IgG2a 3-8
IgG2b 1-2
IgG2c 0.3-2.5
IgA 0.02-0.13
IgD 0.01-0.1
IgE 0.001-0.02
Cheers,
