Analytical ultracentrifugation is a column-free separation technique that measures the relative change in the distribution of molecular weights, providing a way to measure heterogeneity, stoichiometry and self-association of proteins, oligomers, aggregates, particles, colloids, and small structures in solution.
Chirascan is a modern, high performance circular dichroism (CD) spectrometer operating in the ultraviolet and visible wavelength range. It is typically used to probe the secondary structure or conformation of bio-molecules.
Dynamic light scattering measures the diffusion rate of molecules or particles in solution by observing the fluctuations in scattered light from a laser passing through a sample. The sensitivity of DLS increases with increasing molecular size, with a typical lower size limit of 0.5 nanometers and upper size limit of 10 micrometers.
Typical applications for DLS include:
- Screening macromolecules prior to crystallization trials
- Measuring the stability of protein samples for NMR analysis
- Monitoring molecular aggregation
- Characterizing nanoparticles
The DynaPro PlateReader II is set up to make these measurements in 96, 384, or 1536 well plates using as little as 5 microliters of sample.
By determining heat changes associated with binding between any two biomolecules, ITC measures all binding parameters in a single label-free, in-solution experiment.
The Fluorolog 3 is a modular fluorimeter that can be set up to make time-domain fluorescence measurements at specific wavelengths, or steady-state fluorescence measurements over a range of excitation and/or emission wavelengths.
The Xeuss 3.0 offers a maximum flexibility of measurement configurations to get the best possible data quality on any type of sample.
In particular, the following key features enable the user to optimize experiments or results:
- High flux settings adapted for fast kinetics embedded in a low background camera
- Largest surface of detection moveable all the way from WAXS to long distance SAXS to optimize resolution and signal-to-noise
- Long distance SAXS settings for measuring large characteristic dimensions (up to 900 nm depending on the Xeuss 3.0 model)
- Optional USAXS module to characterize large structures ( > 2.5 µm)
