WebJan 24, 2024 · Mass photometry provides the mass distribution of membrane proteins and other sample components at the single-molecule level within a few minutes using very little sample. By quantifying the mass distribution of biomolecules in their samples, researchers gain valuable insights into sample purity, heterogeneity, and protein stoichiometry. 4,5. WebAs part of a reanalysis of galactic Asymptotic Giant Branch (AGB) stars at infrared (IR) wavelengths, we discuss a sample (357) of carbon stars for which mass loss rates, near-IR photometry and distance estimates exist. For 252 sources we collected mid-IR fluxes from the MSX (6C) and the ISO-SWS catalogues.
