SpecificityThe microplate modules are coated with the individual antigens SS-A (Ro), SS-B (La), Sm, RNP/Sm, Scl-70 and Jo-1. All antigen preparations are highly purified by affinity chromatography. The ENA-6-Profile test is specific only for autoantibodies directed to these antigens. No cross-reactivities have been observed.
Intended UseHuman ENA-6 ELISA Kit allows for the in vitro quantitative determination of ENA-6 , concentrations in serum, Plasma , tissue homogenates and Cell culture supernates and Other biological fluids.
StorageFor 5-7days:Store the whole kit at 4℃
For a Long time :Store the Substrate at 4℃, other reagent should store at -20℃.

Product Description specificalPrinciple of the assay: Highly purified antigens SS-A (Ro), SS-B (La), Sm, RNP/Sm, Scl-70 and Jo-1 are bound to micro-wells individually. Antibodies against these antigens, if present in diluted serum or plasma, bind to the respective antigen. Washing of the microwells removes unspecific serum and plasma components. Horseradish peroxidase (HRP) conjugated anti-human IgG immunologically detects the bound antibodies forming a conjugate/antibody/antigen complex. Washing of the microwells removes unbound conjugate. An enzyme substrate in the presence of bound conjugate hydrolyzes to form a blue colour. The addition of an acid stops the reaction forming a yellow end-product. The intensity of this yellow colour is measured photometrically at 450 nm. The amount of colour is directly proportional to the concentration of IgG anti-bodies present in the original sample.
