The Kallestad® Crithidia luciliae Complete Kits are intended for the detection and semi-quantitation of autoantibodies to native DNA (nDNA) antigens using the indirect fluorescence antibody (IFA) procedure. Detection of these autoantibodies is critical in diagnosing and monitoring patients with systemic lupus erythematosus (SLE). Each kit contains all the necessary components for the IFA procedure: Crithidia luciliae substrate slides, FITC conjugate, PBS, mounting medium, negative control, positive nDNA control, Evans blue counterstain and blotters. Wells are spaced for use with a multichannel pipette; controls are pre-diluted and ready to use. Kits are packaged for flexible volume ordering and automation options are available.
