One-stop stability

Cracking stability using a pile of one-trick, protein-hungry tools is a ton of work. Uncle combines 3 different measurement modes — fluorescence, SLS and DLS. So you can crank out all your data in just a few hours, and use way less protein. All the info you’ll get makes picking the best formulation or protein construct a piece of cake. Get brochure.

Trying new formulations or constructs? Get answers for up to 48 samples in under 2 hours. Measure Tm and Tagg at the same time and know when unfolding leads to aggregation. Add a DLS read before the temp ramp to know if you’ve got aggregate trouble right out of the gate.


B22, kD, and G22

Get B22 and kD at the same time in the same Uni. Or, switch over to G22 if you’re working at super high concentrations. Learn on the spot if your protein-formulation combo is good to go or risky for aggregation with software that makes things easy to figure out.


Unleash the Uni

Get more data with way less protein. The Uni only needs 9 μL of sample, and you pick how you use it. Run 1 sample in the morning, 48 in the afternoon. Do a DLS read if that’s all you need. Or, check DLS, then start a 3-day experiment to monitor real-time stability. Your samples are sealed airtight, so runs can be short or long — your call.



Biologics behave differently. With Uncle, you get the whole fluorescence spectrum, so you don’t need to know ahead of time how your protein behaves. No need to add dyes either. Uncle picks up aggregation on two wavelengths — you’ll see both small and large aggregates no matter what.



If you’re working in regulated environments, you know that controlling access to data and keeping its integrity are a must-have. Uncle has 21CFRp11 compliant software tools that can be turned on without a hitch.
