Abstract
The IgG subclass distribution of anti-RNP antibodies was determined in sera from 34 patients. The antibodies were mainly of the complement-fixing IgG1 subclass with minor contributions of IgG3 and IgG4 antibodies. Selected sera contained IgG2 (non-complement fixing) anti-RNP antibodies and may possibly identify a subgroup of patients.
