ELISA Kit Categories

Sandwich Kit
Sandwich kits are fully validated and ready-to-use, containing 96- well strip plates pre-coated with capture antibody to detect sample antigen.


Competitive Kit
In a competitive ELISA assay, sample antigen and labeled antigen compete for capture antibody binding. The more target protein there is in the sample, the less labeled antigen will be captured and the weaker the signal.


Qualitative Kit
Qualitative results provide a simple positive or negative result for a sample. In quantitative ELISA, the optical density (OD) of the sample is compared to a standard curve, which is typically a serial dilution of a known-concentration solution of the target molecule. It is suitable for detecting small antigens


Advantages of our Sandwich kit

Without Diluting Sample

  • Save assay time
  • Wide detection range
  • Reducing non-specific interactions between the sample matrix proteins

Streptavidin-biotin system

  • Significant non-specific binding can be prevented by strepvidin
  • Reducing interference from residual biotin in sample
  • A non-covalent interaction with high affinity

Washing Step

  • Only 5 times for one step

Pre-Coated plate
