  2. Salting out - Wikipedia

    en.wikipedia.org/wiki/Salting_out

    Salting out (also known as salt-induced precipitation, salt fractionation, anti-solvent crystallization, precipitation crystallization, or drowning out) [1] is a purification technique that utilizes the reduced solubility of certain molecules in a solution of very high ionic strength.

  3. Protein precipitation - Wikipedia

    en.wikipedia.org/wiki/Protein_Precipitation

    z i is the ion charge of the salt and c i is the salt concentration. The ideal salt for protein precipitation is most effective for a particular amino acid composition, inexpensive, non-buffering, and non-polluting. The most commonly used salt is ammonium sulfate. There is a low variation in salting out over temperatures 0 °C to 30 °C.

  4. Protein purification - Wikipedia

    en.wikipedia.org/wiki/Protein_purification

    The protein manufacturing cost remains high and there is a growing demand to develop cost efficient and rapid protein purification methods. Understanding the different protein purification methods and optimizing the downstream processing is critical to minimize production costs while maintaining the quality of acceptable standards of homogeneity. [2]

  5. Protein crystallization - Wikipedia

    en.wikipedia.org/wiki/Protein_crystallization

    Microdialysis can produce crystals by salting out, employing high concentrations of salt or other small membrane-permeable compounds that decrease the solubility of the protein. Very occasionally, some proteins can be crystallized by dialysis salting in, by dialyzing against pure water, removing solutes, driving self-association and ...

  6. Hofmeister series - Wikipedia

    en.wikipedia.org/wiki/Hofmeister_series

    The "salting out" effect is commonly exploited in protein purification through the use of ammonium sulfate precipitation. [16] However, these salts also interact directly with proteins (which are charged and have strong dipole moments) and may even bind specifically (e.g., phosphate and sulfate binding to ribonuclease A ).

  8. Ammonium sulfate precipitation - Wikipedia

    en.wikipedia.org/wiki/Ammonium_sulfate_precipitation

    Ammonium sulfate is an inorganic salt with a high solubility that disassociates into ammonium (NH + 4) and sulfate (SO 2− 4) in aqueous solutions. [1] Ammonium sulfate is especially useful as a precipitant because it is highly soluble, stabilizes protein structure, has a relatively low density, is readily available, and is relatively inexpensive.

  9. Kosmotropic - Wikipedia

    en.wikipedia.org/wiki/Kosmotropic

    Ammonium sulfate is the traditional kosmotropic salt for the salting out of protein from an aqueous solution. Kosmotropes are used to induce protein aggregation in pharmaceutical preparation and at various stages of protein extraction and purification.
