Featuring a 38.1 cm (15 inch diagonal), touch-screen display, Optima also boasts formodern, intuitive software for simple run-monitoring and data exports performed either locally or remotely. The optics are contained outside the rotor chamber, making it easier to clean, and reducing the impact of the g-force on the optics.
Chad Schwartz, Ph.D., Product Manager explained: “The new Optima AUC returns analytical ultracentrifugation to the forefront of solution-state protein and particle analysis for accurate molecular weight determination, thermodynamics of associating systems, viral and nanoparticle payload characterisation, and many additional emerging applications.”
Although analytical ultracentrifugation is a recognised technique for protein characterisation, researchers have realised the technology’s value for characterising a wide array of particles including peptides, polymers, metallic nanoparticles, liposomes and other non-biological materials. The Optima AUC allows molecules to float free and unbound so that researchers are able to characterise them in their native state.
Dr. Schwartz added: “Researchers are constantly pushing the boundaries of scientific advancements and require ever more precision and reproducibility from their instruments. The new analytical ultracentrifuge is the result of a successful collaboration with our customers. This latest offering continues Beckman Coulter’s commitment to innovation and provides users with the capabilities they seek to continue their research.
“Rapid data acquisition coupled with reproducible and precise wavelength selections enable applications never before possible with AUC,” said Dr. Schwartz. Wavelength-specific monitoring now allows researchers to study complex systems easily and in a single experiment.”
Product features include:
* Ability to determine molecular weight, size, shape, and polydispersity, and is capable of interactions between particles in a native, matrix-free
environment.
* Multi-wavelength analysis.
* Rayleigh interference system for higher resolution for more precise measurements, higher data density and higher confidence in the results
* State of the art UV-visible absorption optics to provide reproducible wavelength selections, fast radial scanning for reduced temporal distortion, and sensitive detection in the far UV.
Dr. Borries Demeler, University Texas Health Science Center, USA, said: “For the first time, these advanced features enable revolutionary new multi-wavelength experiments, an entirely new class of experimental designs that can exploit the presence of multiple chromophores in complex mixtures through spectral decomposition.
“Coupled with the advanced high-performance UltraScan software, large multi-wavelength datasets can now be rapidly analysed to separate particles in three dimensions, based on size, shape and unique spectral contributions. This will further enhance the unsurpassed power of this analytical technique to help investigators analyse solution properties of complex mixtures without the need for standards.”
