NanoTemper Monolith NT.115
The Monolith allows for rapid and simple molecular interaction measurements (Kd) in solution and in small sample volume using MicroScale Thermophoresis technology.
The Nanotemper Monolith system is designed to measure molecular interactions (Kd) within minutes. Contrary to better known SPR systems with costly consumables and complex immobilization requirements, the Monolith allows measurement of interactions in solution (cell lysates) and small volumes, facilitating sample preparation, staining and scope of experimentation.
MicroScale ThermophoresisTM (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. The main key feature of MST is the capability to work under close-to-native conditions: Measurements are performed immobilization-free and in any buffer, or even in complex bioliquids such as serum and cell lysate. In addition, the method combines straight forward sample preparation, low sample consumption of less than 4 μl per sample at nM concentration, and a large dynamic range with dissociation constants from the sub-nM to mM range. The NanoTemper Technologies Monolith® instruments are maintenance-free, have low running costs and use an intuitive software user interface with provides guided assay development and automated data analysis, making MST a one-of-a-kind, low-hurdle biophysical technology for every lab.

MAGPIX Luminex System
The MAGPIX Luminex System is designed for multiplexing analysis of a large number of analytes for a wide range of applications through commercial or custom designed kits and solutions.
The MAGPIX Luminex system allows for multiplexing analysis of up to 50 analytes using Luminex® xMAP® technology with a wide range of research applications. Commercial kits and solutions for protein and RNA detection assays compatible with the MAGPIX system are available for various manufacturers.
Microsphere beads, either polystyrene or paramagnetic, are color-coded into up to 500 distinct sets. Each bead set can be coated with a reagent specific to a particular bioassay, allowing the capture and detection of specific analytes from a sample. Inside the Luminex® analyzer, a light source excites the internal dyes that identify each microsphere particle, and also any reporter dye captured during the assay. Multiple readings are made on each bead set, which further validates the results. Using this process, xMAP® technology allows multiplexing of up to 500 unique bioassays within a single sample, both rapidly and precisely.
To find kits specific to your research topics and animal models, visit the Luminex Kit Finder site.
