One Workflow, One Sample. **Learn more** Multi-parameter interaction characterization in a single in-solution workflow. When targets are challenging and sample is limited, a binding affinity value is a starting point, not a conclusion. Kd can tell you whether two molecules interact, but it cannot tell you how quickly binding happens, how long a complex remains intact, or whether your target stays stable under assay conditions. Those questions matter in drug discovery, protein biochemistry, and molecular interaction research. Monolith Omni was built to help answer them in one workflow with minimal sample consumption. ##### What is Monolith Omni? Monolith Omni is a benchtop biophysical platform from NanoTemper Technologies that combines affinity, kinetics, and qualitative stability analysis in a single in-solution workflow. It is a new addition to the Monolith platform, designed to help researchers build a more complete picture of biomolecular interactions - from the same sample, without additional material. The result is broader interaction data across challenging targets, even when sample is limited. "Monolith Omni isn't just a product launch, it opens a new chapter for NanoTemper. It helps scientists move beyond data collection toward a deeper understanding of molecular interactions, with less friction, less sample, and a faster time to insight. For teams working on tough questions, that's a meaningful step forward." — Dr. Stefan Duhr, CEO, NanoTemper Technologies ##### Why isn't affinity measurement alone enough? Affinity (Kd) tells you the strength of a binding interaction, but it doesn't explain how quickly a molecule binds, how long it remains bound, or how stable your target is under assay conditions.These parameters, kinetics and stability, are often decisive in drug discovery and molecular research. - Kinetic rates (kon, koff) reveal whether a drug candidate binds fast enough and stays bound long enough to be therapeutically relevant. - Stability data shows whether your target is folded and functional, and whether a ligand stabilizes or destabilizes it. - Orthogonal confirmation increases confidence in hits and candidate decisions. Two compounds can show similar affinity and still behave very differently in practice. One may bind quickly and dissociate just as fast. Another may show longer residence time or stabilize the target in a way the first does not. In academia, this can help researchers better understand mechanism and binding behavior. In biopharma, it can support hit validation, lead optimization, and candidate selection. Monolith Omni brings these layers of information together in one in-solution workflow. ##### How does Monolith Omni measure kinetics in solution? A defining capability of Monolith Omni is in-solution kinetic characterization using nanoTAK (nano Temperature Alteration Kinetics). Unlike traditional surface-based methods such as SPR or BLI, Monolith Omni measures interactions in solution, without immobilizing either binding partner. This helps reduce surface-related effects and mass-transport limitations that can complicate interpretation in surface-based assays. nanoTAK takes a first-principles and well characterized and accepted approach to kinetics measurement by perturbing a pre-equilibrated sample and monitoring its shift to a new equilibrium position in real time. A rapid and precise shift in sample temperature is created using an IR laser, perturbing the equilibrium, and the resultant changes in Spectral Shift report the resulting relaxation behavior, from which kinetic rate constants can be extracted, fully in solution. ##### What types of targets can Monolith Omni characterize? Monolith Omni is designed for challenging targets and diverse molecular modalities that are difficult to measure with surface-based methods.Supported targets include: - Membrane proteins - in detergent, nanodiscs, or complex unpurified matrices - Intrinsically disordered proteins (IDPs) and transcription factors - Nucleic acids - DNA, RNA, aptamers, antisense oligonucleotides - Small molecules and fragments, including weak binders in the mM range - Molecular glues, PROTACs, and degraders - including ternary complex cooperativity and hook effect analysis - Covalent inhibitors - measured at equilibrium via direct biophysical readout ##### Why is Monolith Omni well suited for sample-limited experiments? When material is scarce, every microliter matters. Monolith Omni is designed to help researchersWhen material is scarce, every microliter matters. Monolith Omni is designed to help researchers generate more insight from less sample. - 10 µL of sample per capillary - Up to 24 capillaries per run - Multiple readouts from the same sample This low sample requirement is especially valuable for difficult-to-express proteins, precious purified material, membrane proteins, and early-stage candidate molecules available only in limited quantities. ##### How quickly can labs bring Monolith Omni into their workflow? Monolith Omni is designed for straightforward onboarding. Installation and user training can be completed in a single day, and the workflow is supported by guided software for assay setup, optimization, and real-time data acquisition. Single-use capillaries help avoid cross-contamination and reduce maintenance, while the fluidics-free design keeps the workflow simple. ##### Who is Monolith Omni for? Monolith Omni is designed for researchers in academia and biopharma who need more than affinity data to make confident decisions about their candidates.It is particularly well suited when: - Your target is challenging: membrane protein, IDP, nucleic acid, or a modality that struggles with surface immobilization. - Sample is limited and needs to go as far as possible. - You're working with molecular glues, PROTACs, or degraders where ternary complex kinetics matter. - You need orthogonal hit confirmation without running a separate experiment. - You want kinetic context to support lead optimization decisions. It supports workflows from early hit validation through lead optimization, as well as broader molecular interaction studies in academic research. **Read Data file** ##### FAQs What does Monolith Omni measure? Monolith Omni measures binding affinity (Kd), kinetic rate constants (kon/koff), thermodynamic parameters via Van’t Hoff analysis, and qualitative protein stability in solution within a single workflow. How is Monolith Omni different from other kinetics platforms? Unlike surface-based kinetics platforms such as SPR or BLI, Monolith Omni measures interactions in solution without immobilizing either binding partner. This helps reduce surface-related artifacts, supports challenging targets, and enables kinetic analysis in a fluidics-free workflow. How much sample does Monolith Omni require? Each measurement requires 10 µL of sample per capillary, with up to 24 capillaries per run. Can Monolith Omni measure membrane proteins? Yes. Monolith Omni supports membrane protein characterization in detergent, nanodiscs, or complex unpurified matrices, which can be challenging for some surface-based methods. Can Monolith Omni measure molecular glues and PROTACs? Yes. Monolith Omni supports analysis of heterobifunctional degraders, including binary and ternary complex affinities, cooperativity, and hook effects. Is Monolith Omni suitable for high-throughput screening? Monolith Omni is designed for deep, multi-parameter characterization rather than large-scale screening. It is best suited for applications where interaction quality, limited sample, and workflow simplicity are priorities. Where can I learn more or request a demo?
