Synthetic polypeptide antigens
-branched multichain synthetic polypeptides
-not defined structures
-(T,G)-A-L; (H,G)-A-L; (P,G)-A-L
R=poly (tyrosine,glutamine acid
=poly (histidine,glutamic acid)
=poly (proline,glutamic acid)
Michael Sela-Weissman Institute for Sciences, Rehovot, Israel
1948- George Snell (The Jackson Laboratory)
Identified 2 types of loci:
Major (strong) = H-2
Minor (weak) = non-H2
i.e. H-1, H-4, H-Y
“Speed congenics” decrease the number of
backcross generations by typing each chromosome for background strain alleles and selecting mice to breed which have the highest number of background genes.
Inbred stains of guinea pigs
