Porex TruFlowTM Conjugate Pads

Optimized for Consistency and Manufacturing Ease

Porex TruFlowTM conjugate pads consistently and efficiently absorb and release for more accurate downstream detection

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. Porex TruFlowTM conjugate pads have demonstrated complete release for varying types of labels, including gold or latex.

The robustness of the material ensures an easy adaption for reel-to-reel applications, as well as soaking and spraying processing steps. Porex TruFlow conjugate pads do not include any glass fiber or cellulose, which ensures increased strength and durability for manufacturing.
