Tycho named one of the Top 10 Innovations of 2018 by The Scientist

Protein quality is key to getting consistent results

Most of the time, you don’t know something’s wrong until you’re several steps into your experiment and you see inconsistent results. What if you could simply check the quality of your sample before you even start? That’s where Tycho comes in.


Tycho NT.6

Tycho tells you so much about the quality of your protein

It tells you about presence, purity, concentration, functionality and similarity — in a single experiment. These can all be measured simply by determining whether your protein is structurally intact or properly folded.

Analyze under native conditions
There’s no need to fluorescently label or modify your sample — that means no assay development and only real results.

Get answers in minutes
Generate informative data in just 3 minutes  — it makes deciding what to do next that much easier. Watch video

Easily test any protein sample type
Forget dialyzing or doing sample dilutions. Determine the quality of any protein in any type of buffer over a wide range of concentrations.

Save scarce bench space
Tycho’s small footprint doesn’t take up a lot of bench space which means more space for you!

Conserve precious sample
Purifying protein because you’ve run out of sample is like 🤦‍♂️or 🤦‍♀️. Not only can checking your protein’s quality help you run less experimental parameters later, but you only need 10 µL of sample.

I put every protein in Tycho first. The data is very reproducible in our hands. Just mix your samples, put the capillaries in and 3 minutes later you have your results.  It’s the only equipment I would recommend to anyone working on proteins because there are no downsides in having a Tycho.

How does Tycho identify sample quality?

Tycho verifies protein quality by looking at the structural integrity (or foldedness) of a protein. As a thermal ramp is applied, the changes in the intrinsic fluorescence, detected at both 350 nm and 330 nm, from tryptophan and tyrosine residues in the protein are measured. These changes in fluorescence signal indicate transitions in the folding state of a protein. The temperature at which a transition occurs is called the inflection temperature (Ti). The fluorescence is recorded during the thermal run, plotted as ratio and used to calculate Ti. Its initial value along with the change in signal over the run (Δ ratio) is also recorded.

Verify the quality of your starting material or similarity between batches

With Tycho, compare the structural integrity or unfolding profile of that new sample prep to your reference sample of the right quality to verify they are similar. If they differ, you may have a sample of lower quality that contains contaminants—this indicates the need to further purify it or optimize your purification workflow. Having confidence that you are working with the highest quality samples all the time, will result in more consistent results.

Check for sample presence, amount and purity

Once you’ve run Tycho to confirm results from traditional methods, you’ll realize that the results from Tycho not only show you the presence of your protein but also if impurities are present. And, it even lets you determine the concentration of it. So in the future, shelve those traditional methods that take time and use up a lot of your precious material.

Precise and Concentration

Monitor Purity

Determine the right buffer recipe for storage or assay development

Use Tycho to identify the right buffer recipe for storage or assay development to preserve the quality of your protein. Quickly screen different buffers, additives and excipients as well as storage temperatures and time periods to determine the right conditions for your protein samples. Use this information to help optimize your assay conditions for future experiments. In the end, you’ll spend less time generating unnecessary batches of protein.

Monitor Storage Conditions

Quickly confirm functionality

Tycho tests functionality in 3 minutes and tells you if your protein is interacting with other molecules. Since it does this in a label-free way with very little sample, it’s much easier than traditional methods, so now there’s no reason why you wouldn’t do it earlier.

Test Functionality

Know protein quality early on

During monoclonal antibody therapeutic development, knowing structural integrity as early as possible is one of the strongest indicators of functionality and potential drug efficacy.

A monoclonal antibody (Herceptin) was treated with two oxidation conditions and run on Tycho to test the effects of the treatment on sample quality. A longer oxidation treatment caused more unfolding of the mAb as indicated by the increased initial ratio reading. In addition, increased oxidation treatment causes a left shift in the detected first inflection temperature suggesting possible structural changes to particular domains in the protein (left). MicroScale Thermophoresis (MST) was performed to confirm the effect oxidation treatment can have on Herceptin binding affinity (right).

Hit the bench running

Using Tycho is super easy — just follow the onscreen prompts to start an experiment. Assign names to your samples while your experiment is running to keep your records in order. When it’s done, simply export both the raw data, automatically analyzed results, and summary figures in a convenient ready-to-share format.


Tycho Capillaries

Small amounts of sample is all you need

You can do so much (or so little) using Tycho and minute amounts of sample. Accurate results are obtained using tiny, precisely constructed glass capillaries so analysis can be done on virtually any sample type. No pipetting is required since sample is taken up by capillary force directly into the capillary, so you’re not wasting your precious sample.
