Frequently Asked Questions (FAQs)

We work to your defined assay specifications. If you don’t have these, we have ecosystem partners who can help. 

Formulations and enzymes/proteins can be engineered by our team to increase sensitivity. 

We manufacture under ISO 13485. 

Earlier engagement changes what’s achievable and you should have developed your preliminary specifications. Reagent selection, format decisions, and detection chemistry all create downstream constraints.
