Nanotemper Monolith – Microscale Thermophoresis Binding Affinity (MST)
MicroScale Thermophoresis determines binding affinities in solution. It measures the motion of molecules along microscopic temperature gradients and detects changes in their hydration shell, charge or size.
Time and cost effectiveness
- fast measurement: Kd in 10 min
- low sample consumption: minimal concentration (pM/nM) and small volume (< 4 µl)
- intuitive software
- small instrument footprint, maintenance free
Easy sample preparation
- immobilization free, in-solution measurements
- truly label-free (optional)
- excellent selectivity using a fluorescent dye or fluorescent protein
Broad application range
- access affinities (Kd, dissociation constant): pM/nM to mM range
- examine: proteins, peptides, ribosomes, ions, nucleosomes, liposomes and more
- study membrane proteins directly in liposomes or detergent solution
- study multi-component reactions such as ternary complex formation, order of assembly, interfering factors, cooperativity
- measure in any buffer, including complex detergent mixtures
- study stoichiometry and discriminate between different binding sites on a target
- study the binding energetics ΔG (free energy), ΔH (enthalpy) and ΔS (entropy)

Nanotemper Tycho – When protein quality matters.
Quickly identify the quality of any protein using microliters of sample with Tycho
Finding out the quality of your protein up front will help you figure out if it’s functional, similar to the previous batch you made, or properly stored. With very little effort, you’ll make sure you’re moving forward with a viable sample, and save yourself from doing have-to-repeat-it-again experiments.
Quickly verify protein quality
Ever wonder if your protein is the same as it was a day or a year ago? Is it even present? Confirm sample quality at any point in your workflow so you know you still have the right protein.
Get answers in minutes
Generate informative data in 3 minutes fast — it makes deciding what to do next that much easier.
Easily analyze 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.
Conserve precious sample
Purifying protein for the umpteenth time because you’ve run out of sample is painful. Not only can checking your protein’s quality help you run less experimental parameters later, but it only requires microliters of sample for analysis.
Small benchtop footprint
Save scarce bench space for handwork while getting valuable info from a powerful system with a tiny footprint.
