  • 本試劑盒所含材料：
      • A micro ELISA plate --- The 96-well plate has been pre-coated with anti-human Aβ1-42 antibody. This dismountable microplate can be divided into 12 x 8 strip plates.
      • Two vials lyophilized standard --- Dilute a bottle of standard at dilution series, read the OD values, and then draw a standard curve.
      • One vial Biotin-labeled Aβ1-42 antibody (100 x concentrate) (120 μl/bottle) ---Act as the detection antibody.
      • One vial HRP-avidin (100 x concentrate) (120 μl/bottle) --- Bind to the detection antibody and react with the TMB substrate to make the solution chromogenic.
      • One vial Biotin-antibody Diluent (15 ml/bottle) ---Dilute the high concentration Biotin-antibody to an appropriate working solution.
      • One vial HRP-avidin Diluent (15 ml/bottle) ---Dilute the high concentration HRP-avidin solution to an appropriate solution.
      • One vial Sample Diluent (50 ml/bottle)---Dilute the sample to an appropriate concentration.
      • One vial Wash Buffer (25 x concentrate) (20 ml/bottle) --- Wash away unbound or free substances.
      • One vial TMB Substrate (10 ml/bottle) --- Act as the chromogenic agent. TMB interacts with HRP, eliciting the solution turns blue.
      • One vial Stop Solution (10 ml/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

靶點詳情

  • 最新研究進展：
    Aβ1-42是β淀粉樣蛋白（amyloid beta protein，Aβ）的一種亞型，它是導致阿爾茨海默病（Alzheimer's disease，AD）的主要病理因素之一。最新的研究表明，Aβ1-42的聚集和沉積不僅在AD中發揮作用，而且在其他神經退行性疾病中也可能具有重要作用，如前額顳葉癡呆癥、帕金森氏病等。
