Phosphate-buffered saline (PBS) is a buffer solution (pH ~ 7.4) commonly used in biological research. It is a water-based salt solution containing disodium hydrogen phosphate , sodium chloride and, in some formulations, potassium chloride and potassium dihydrogen phosphate .
31 sie 2022 · The structures contain a previously undescribed linker protein that binds to the membrane-facing side of PBS. For the unquenched PBS, the structures also reveal three different...
17 wrz 2021 · Phycobilisomes (PBS) are the major light-harvesting machineries for photosynthesis in cyanobacteria and red algae and they have a hierarchical structure of a core and peripheral rods, with both...
4 cze 2023 · Phycoerythrin subunits mainly use phycoerythrobilin (PEB) or phycourobilin (PUB) that contribute to the 560 nm light absorbance. The heterogeneity of the spectral properties of PBPs enables the PBS to collect excitation energy from the rods and funnel it to the photosynthetic reaction centre.
13 cze 2018 · PBs are constitutively present in mammalian cell lines and appear as droplets averaging 0.5 μm in diameter, with ten or fewer per cell (Figure 1A) . Electron microscopy imaging shows that they are devoid of membrane and have a fibrillogranular ultrastructure (Figure 1B) .
28 sty 2019 · PBS or phosphate-buffered saline is a buffer solution that is particularly valuable because it mimic the ion concentration, osmolarity, and pH of human body fluids. In other words, it's isotonic to human solutions, so it's less likely to cause cell damage, toxicity, or unwanted precipitation in biological, medical, or biochemical research.
16 gru 2020 · In this work, we proposed to use a linear system with switching methodology to describe and analyze complex biological systems. This allows for a much simpler description of the system, with only linear equations and few threshold definitions, while retaining complex dynamics.
