Preface This manual is your guide for using the Monolith NT.115 and doing MicroScale Thermophoresis (MST) measurements. It instructs first-time users on how to use the instrument, and serves as a reference for experienced users. Before using the Monolith NT.115 instrument, please read this instruction manual carefully, and make sure that the contents are fully understood.
Limited Warranty Products sold by NanoTemper Technologies, unless otherwise specified, are warrantied for a period of one year from the date of shipment to be free of defects in materials and workmanship. If any defects in the product are found during this warranty period, NanoTemper Technologies will repair or replace the defective part(s) or product free of charge.
(RH), condensation may deteriorate optical components. Operate the instrument in an atmospheric pressure range of 800 – 1060 hPa. 10. Do not operate the Monolith NT.115 under conditions which pose a risk of explosion, implosion or the release of gases.
Connecting the power supply and the Monolith NT.115 Confirm that the power switch of the Monolith NT.115 instrument is off (power switch is at the back, left of the instrument).
Malfunction In case of a malfunction switch off the Monolith NT.115 instrument and wait for five minutes, then switch on the instrument again. If the malfunction persists switch off the device, unplug the power cable and contact the NanoTemper Technologies customer support.
1. Introduction to MicroScale Thermophoresis (MST) MicroScale Thermophoresis (MST) provides an easy, fast and precise approach to quantify biomolecular interactions. It allows for the detection of a wide range of interaction types, ranging from ion and fragment binding up to interactions of macromolecular complexes such as liposomes or ribosomes [1-3].

In some cases, the fluorescence of the target molecule changes upon ligand binding even in the absence of an IR-induced temperature gradient. These cases can be analyzed using the Fluorescence Analysis Mode. The phenomenon is referred to as ligand-induced fluorescence quenching or enhancement and is typically caused by changes in target conformation or binding of the ligand in proximity to the target’s fluorophore(s).

where [A] is the concentration of free fluorescent molecule, [L] the concentration of free ligand and [AL] is the concentration of the complex of A and L. The free concentrations of A and L are [A]=[A [AL] and [L]=[L ]-[AL], respectively. [A ] is the known concentration of the fluorescent molecule and ] is the known concentration of added ligand.
1.1.4. Software MST experiments are analyzed using the dedicated MO.Control and MO.Affinity Analysis Software, using the above equations. Prior to determining binding affinities, the MO.Control software performs several automated quality checks of the samples to detect protein adsorption, aggregation, or other irregularities. Based on the results, a guided assay development algorithm provides detailed instructions on how to efficiently improve assay quality (if necessary).
= 1 nM - 500 mM). 2.3. Sensitivity The Monolith NT.115 can measure as little as the binding of single ions (40 Da) or small molecules (300 Da) to a target as well as the binding of large complexes such as ribosomes (2.5 MDa).
2.5. Capillary Format The capillary format used for the Monolith NT.115 is inexpensive, easy to handle and offers maximum flexibility in the experiment scale. The standard sample tray format allows automatic processing of up to 16 capillaries (e.g. for a detailed K analysis).
3.1. Control Kits - Performing Standard Experiments Control Kits containing standardized sample material are recommended when using the Monolith NT.115 instrument for the first time for monitoring the correct performance of the Monolith NT.115 for training of new laboratory members Optimized Control Kits for use in MicroScale Thermophoresis are available either with red- or green- fluorescently labeled biomolecules.
3.3. Fluorescence Labeling The following kits offer optimized fluorescence labeling and purification protocols for use in MicroScale Thermophoresis. The dyes have been widely tested with MST and the protocols are optimized to remove free, non-reacted dye: Cat # Protein Labeling Kits Reactions Monolith L001...

Place the sample tray in the instrument by pushing it into the tray slot of the instrument as far as possible. The Monolith NT.115 instrument scans the tray and automatically determines the position of the capillaries on the tray.
4. Using the Monolith NT.115 Instrument Turn on the Monolith NT.115 instrument using the power toggle switch on the back of the instrument and start the control notebook. The display of the Monolith NT.115 instrument will show the following screen: The words “Ready”...
