Features & Benefits
Human Uveal autoantigen with coiled-coil domains and ankyrin repeats (UACA) ELISA Kit has high sensitivity and excellent specificity for detection of Human UACA. No significant cross-reactivity or interference between Human UACA and analogues was observed.
Background
Using a human sequence homologous to the bovine UACA sequence to screen a Jurkat cell cDNA library, they isolated the human homolog, which was found have the same sequence as KIAA1561. Human UACA encodes a deduced 1,449-amino acid protein with a predicted molecular mass of approximately 166 kD. It contains 6 ankyrin repeats, a leucine zipper motif, and coiled-coil domains. The bovine and human proteins share 86% sequence homology. Northern blot analysis demonstrated expression at various levels in all tissues analyzed, with highest expression in skeletal muscle.the prevalence of IgG anti-UACA autoantibodies in patients with panuveitis was significantly higher than that in healthy controls (19.6-28.1% vs 0%, p less than 0.05), indicating that autoimmunity directed against UACA is a common phenomenon in these diseases.
This Uveal autoantigen with coiled-coil domains and ankyrin repeats (UACA) ELISA kit is validated for use with Cell culture supernatants, Serum, Plasma, Other biological fluids. Samples should be collected, processed, and stored correctly to preserve analyte integrity — avoid repeated freeze-thaw cycles and centrifuge to remove particulates before use. Dilute samples exceeding the kit's detection range using the supplied assay diluent. Hemolytic, icteric, or lipemic samples may affect assay performance and should be tested with caution.
This is a sandwich ELISA kit employing an HRP (horseradish peroxidase)-conjugated secondary antibody paired with a TMB (3,3′,5,5′-tetramethylbenzidine) colorimetric substrate. In the sandwich format, the target analyte Uveal autoantigen with coiled-coil domains and ankyrin repeats (UACA) captured on the microplate surface is detected by the conjugated antibody, generating a colorimetric signal proportional to analyte concentration. The reaction is stopped and absorbance measured at 450 nm on a standard microplate reader.
The complete protocol, from sample addition to final plate reading, requires approximately 3–5 hours. This includes two incubation periods (analyte binding and detection antibody steps), intermediate wash cycles to remove unbound material, 15–30 minutes of TMB substrate development, and final stop-solution addition before absorbance reading. Exact timing will vary with experience level and the number of samples processed in parallel.
Required equipment: (1) a microplate spectrophotometer capable of reading absorbance at 450 nm (reference wavelength 540–570 nm recommended for background correction); (2) precision single-channel or multichannel pipettes; (3) a plate washer or multichannel aspirator; (4) a microcentrifuge for sample clarification; and (5) a 37°C incubator or stable room-temperature environment. No fluorescence or luminescence reader is required — standard colorimetric plate readers are fully compatible with this kit.
This ELISA kit is formally validated for Human. Cross-reactivity with species not listed in the specification has not been independently characterized. Variability in protein sequence homology across species means that performance in unlisted species cannot be guaranteed without additional validation.
