title: Amino acid sequence analysis of group e allotype-related peptides derived from lagomorph IgG.
abstract: A tryptic peptide (T 19) was isolated from a CNBr fragment of IgG from several representatives of present-day lagomorphs including domestic rabbit, hare, cottontail rabbit and pika. The amino acid sequence of this peptide revealed differences which can be correlated with serological polymorphism associated with group e IgG allotypes. The results confirm previous studies establishing the importance of Ala309 for the expression of e 15, particularly the i subspecificity. Arg315 correlates with the expression of the j subspecificity.
