Conjugate pads consistently and efficiently absorb and release for more accurate downstream detection

Conjugate Pad Material

The conjugate pads in lateral flow assays (LFA) absorb functionalized conjugate and release it efficiently and reproducibly when the assay is run. Therefore, consistent uptake and release rate of the conjugate, as well as diminished non-specific binding, are key requirements. One of the most important influences from the conjugate pad material is its play in developing a consistent control and test line in every single test. We offer a synthetic polyolefin fiber that consistently and efficiently absorbs and releases conjugate to allow for accurate downstream detection. The robustness of the material ensures an easy adaption for reel-to-reel applications, as well as soaking and spraying processing steps.

  • Complete release of conjugate generating strong test and control line signal
  • Robust material, ensuring an easy adaption for reel-to-reel applications
  • Superior tensile strength when wet; ideal for soaking or spraying processing
  • Improved material consistency, both within lot and lot-to-lot
