Celiac EmA (Anti-Endomysium Antibody) ELISA assay kit is an enzyme immunoassay for the quantitative determination of IgA autoantibodies to the supposed major autoAntigenss in Dermatitis herpetiformis and celiac disease in sample serum. Sample Types: serum. Range: 1 - 300 U/ml. Sensitivity: 1 U/ml. Time: 2 hours ? Several autoAntigenss have been discussed for celiac disease and Dermatitis herpetiformis recently. Dieterich et al. have described two non-collagenous proteins with an apparent molecular weight of 90 and 300 kDa being the main autoAntigenss detected by EmA (1).
