Extractable nuclear antigen (ENA-6) are intending for profiling one or more autoantibodies that has the ability to react with proteins within the cell nucleus. These are vital in helping to diagnose autoimmune disorder and aiding in distinguishing between different disorders, this is possible because one or more anti-ENA antibodies are found to be associated to specific autoimmune disorders. The ENA profile assay can be either an ENA-4 or an ENA-6 autoantibody tests. The 6-test ENA profile will include anti-Sm, anti-SS-A (Ro), anti-SS-B (La), anti-RNP, Scl-70 and Anti-Jo-1.
Human ENA-6 ELISA kit is a procedure for profile screening in-vitro quantitative levels of IgG autoantibodies to extractable nuclear antigens (ENAs) in human serum and plasma samples. This assay has a minimum analytical sensitivity limit of diagn. 86.4%.
Extractable nuclear antigens Sm, RNP/Sm, Jo-1, SS-A (52 and 60 kDa), SS-B and Scl-70 are bound to the microwells.
The minimum detection sensitivity level of human extractable nuclear antigen profile (ENA-6 profile) using this human ENA-6 ELISA kit was diagn. 86.4%. The dynamic assay range for this kit is to a cut-off index 1.0.
