WebThe conditions to precipitate these proteins are raising the ethanol concentration from 18 to 40% and raising the pH from 5.2 to 5.8. Finally, albumin is located in fraction V. The precipitation of albumin is done by reducing the pH to 4.8, which is near the pI of the protein, and maintaining the ethanol concentration to be 40%, with a protein ... WebJan 31, 2024 · Finally, RTX polymerase was precipitated by the addition of ethanol to a final concentration of 50%. The tubes were incubated on ice for 1 h, and the precipitated protein was resuspended in 10 mL of storage buffer (50 mM Tris-HCl, pH 7.9, 50 mM KCl, 0.1 mM EDTA, 1 mM DTT, 0.1% Nonidet P40, 0.1% Tween 20, 50% glycerol).
