Materials provided
  • A micro ELISA plate ---The 96-well plate has been pre-coated with an anti-human SIgA antibody.
  • Two vials lyophilized standard ---Dilute a bottle of the standard at dilution series, read the OD values, and then draw a standard curve.
  • One vial HRP-conjugated SIgA antibody (100 x concentrate) (120 μl/bottle) ---Bind to the CEA in the samples or standards and react with the substrate to make the solution chromogenic.
  • Two vials Sample Diluent (20 ml/bottle)---Dilute the sample.
  • One vial Wash Buffer (25x concentrate) (20 ml/bottle) ---Wash away unbound or free substances.
  • One vial TMB substrate (10ml/bottle) ---Interact with TMB to elicit a chromogenic reaction.
  • One vial Stop Solution (10ml/bottle) ---Stop the color reaction. The solution color immediately turns from blue to yellow.
  • Four Adhesive Strips (For 96 wells) ---Cover the microplate when incubation.
  • An instruction manual
