Lateral Flow Assays Development

Kimialys supports your LFA development end-to-end.



The most critical steps in LFA development are antibody selection and detection label optimization, as they play a major role in the final assay sensitivity, specificity, and reproducibility. At Kimialys, we leverage our technology and know-how to deliver optimal results for those keys steps:

Fast and reliable antibody selection with our multiplexed SPRi platform.

Gold bioconjugate optimization leveraging our K-One® surface chemistry.

Beyond that, our research engineers will assist you throughout the project to fine-tune key parameters of assay design, helping you reach your target performance.
