  • 本试剂盒所含材料:
      • An assay plate --- The 96-well plate is composed of 12 x 8 strip plates and can be taken apart.
      • Two bottles of lyophilized standard --- Reconstitute one bottle of the standard with sample diluent at dilution series and draw the standard curve.
      • Biotin-labeled LPS antibody (100 x concentrate) 1 x 120 μl --- Act as the detection antibody and need to be diluted before use.
      • HRP-avidin (100 x concentrate) 1 x 120 μl --- Catalyze the TMB substrate for color development and need to be diluted before use.
      • Biotin-antibody Diluent 1 x 15 ml --- Dilute the Biotin-antibody.
      • HRP-avidin Diluent 1 x 15 ml --- Dilute the HRP-avidin.
      • Sample Diluent 1 x 50 ml --- Reconstitute the standard and dilute the sample to an appropriate concentration.
      • Wash Buffer (25 x concentrate) 1 x 20 ml --- Wash away the unbound solution and non-specific substances.
      • TMB Substrate 1 x 10 ml --- Act as the chromogenic agent. HRP catalyzes TMB, eliciting the solution turns blue.
      • Stop Solution 1 x 10 ml --- Add stop solution and stop the color development. The solution color immediately turns from blue to yellow.
      • Four Adhesive Strips(For 96 wells) --- Seal the microplate when incubation.

 常见问题解答
Q:

为什么不同的物种有不同的ELISA试剂盒。是因为LPS的变化吗?我可以用人LPS ELISA检测小鼠血浆中的LPS吗?

A:
不建议跨物种检测。因为不同物种基质是不同的。
