CRYSTAL-INDUCED INFLAMMATION IN CANINE JOINTS

Abstract

Two types of γG4 proteins, termed 4a and 4b, were characterized through antigenic studies of myeloma proteins. Both were recognized by specific antigens on the Fc fragment which were shared with other γG classes. The distinctive antigen of the common 4a type was shared with all γG1 and γG3 proteins but missing in those of the γG2 class; that for the rarer 4b type was selectively found in proteins of the γG2 class.
