This is part of problem 5. What is the thermal voltage VT at…
In the fоllоwing prоcedure, the protein of interest, CA, is initiаlly concentrаted by precipitаtion from a 30% saturated ammonium sulfate solution. If you were interested in using ammonium sulfate precipitation to isolate a highly charged peptide, would you expect the peptide to precipitate from a low or high concentration ammonium sulfate in solution? Briefly justify your answer. Procedure from the reference cited below: “Briefly, cells expressing the wild-type CA protein were lysed through a microfluidizer. Soluble CA protein in the clarified lysate was concentrated by precipitation from 30% saturated ammonium sulfate. CA protein was redissolved in 50 mM Tris (pH 8.0) and functionally purified by the addition of sodium chloride to a final concentration of 2.5 M. After two rounds of functional purification, the wild-type CA protein was resuspended in 50 mM sodium phosphate buffer (pH 7.5) and dialyzed against the same buffer. The dialyzed sample was further purified by a subtractive anion exchange chromatography step using a Q-HP HiTrap column (catalog no. 17-1154-01, GE Healthcare, Piscataway, NJ). Purification of 2Mut and 4Mut CA mutants followed the same protocol that was used for wild-type CA except that 200 mM β-mercaptoethanol was included in all buffers throughout the process. The functionally purified capsid mutant proteins were redissolved in 50 mM Tris (pH 7.5) and 40 mM β-mercaptoethanol prior to dialysis in the same buffer, and a subsequent purification with subtractive anion exchange chromatography was performed.” Tsiang, M., Niedziela-Majka, A., Hung, M., Jin, D., Hu, E., Yant, S., Samuel, D., Liu, X., & Sakowicz, R.
