We spike well-known promoters into each screen as references, so every candidate is reported relative to elements you already know. This lets you judge our promoters against your current benchmark directly rather than in the abstract.

Specificity comes from comparison, so we counter-screen candidates against the off-target cell types you want to avoid, not only the target cell. An element is only called specific when it is active where you want it and quiet where you do not want expression. 

Yes, you can evaluate an off-the-shelf promoter under an evaluation agreement before committing to a full license, so you can confirm it performs in your system first. 

Yes. You do not have to hand over your proprietary vector backbone to us. We typically work through a third-party cloning service, so neither party has to share sequences they want to keep confidential. 

Yes, we work from standard evaluation and material-transfer templates and can send them early so your legal team reviews in parallel. Evaluation periods are typically 6 months and, unless agreed otherwise, run from when you receive the material rather than from signing, so cloning or vector production does not eat into your time. We set the exact window in the agreement.
