1. The buffer system The pH of the solution is critical. Proteins may precipitate or become unstable when the pH is outside of the physiological range. To avoid this situation, a buffer system such as Tris-HCl is recommended. Besides buffering solutions in this range, a Tris-HCl buffer pre...
How many mL of 4.4 M HCl solution must be added to 3.1 L of a 0.20 M K2HPO4 solution to prepare a buffer with a pH of 7.43? How many milliliters of 4.2 M HCl must be added to 3.1 L of 0.16 M K2HPO4 to prepare a...
A 100.0 mL of a buffer solution is prepared from 0.25 M {eq}CH_3NH_2 {/eq} and enough HCl to adjust the pH of 10.50. What is the ratio of the {eq}CH_3NH_2 \text{ to } CH_3NH_3^+ {/eq} in the buffer? {eq...
Optimized crystals at a size of 100 × 100 × 70 µm appeared in about 4 to 5 days at 15 °C in drops containing 0.1 M Tris/HCl (pH 8.0), 0.2 M MgCl2, and 8% PEG 8000 solution. DYRK1A protein in complex with abemaciclib was crystallized with 14–16% PEG...
