Description
The object of the procurement is a mass photometry system. Biocenter Oulu seeks a label-free optical measurement system which is capable of nanoparticle, including protein, molecular mass and mass distribution determination in native state (without surface immobilisation) with single molecule detection sensitivity/resolution, including possibility to measure high concentration samples. The system is used to study oligomerization state, biomolecular interactions, polymerization, sample composition, and purity. The mass photometer device must be able to measure mass of various biological nanoparticles including proteins and nucleic acids up to 20 nm size and with low sample amount. The system must enable measurement of different kinds of samples including high concentration (tens of micromolar) protein solutions. The mass photometry device must utilise attenuated optical interferometric back-scattering microscopy with reduction of signal to noise or signal to background ratio to determine mass of individual particles and mass distribution of a sample. When calibrated against known masses of same refractive index, the mass of unknown sample with similar refractive index is calcula…
