title: Application of protein-A indirect ELISA (PAI-ELISA) for the detection of anti-Smith antibodies in systemic lupus erythematosus patients.
abstract: An indirect form of protein-A ELISA (PAI-ELISA) was optimized and, when used to detect anti-Smith antibodies in sera of 31 systemic lupus erythematosus (SLE) patients, gave results comparable with those using a commercial immunodiffusion kit. The number of sera found to be positive for anti-Smith antibodies by ELISA was seven, four of which were also found positive by immunodiffusion.
