WebDec 5, 2024 · Figure 8.6. 2: The Calvin cycle has three stages. In stage 1, the enzyme RuBisCO incorporates carbon dioxide into an organic molecule. In stage 2, the organic molecule is reduced. In stage 3, RuBP, the molecule that starts the cycle, is regenerated so that the cycle can continue. In summary, it takes six turns of the Calvin cycle to fix six ... WebA solution ranging from 1-4% PFA is typically used for fixation of samples for flow cytometry. In the case of sanitizing infectious samples, concentrations as low as 0.37% can effectively disinfect samples from …
WebUltimately, how can these decisions potentially affect my flow staining? In this blog, we'll explore these questions related to fixation, and perhaps some food for thought for your next flow cytometry experiment when you … WebControls will require fixation using the same procedure. Cells should not be fixed if they need to remain viable. There are several methods available, please refer to the fixation section in the indirect staining protocol. The …
