Isolation of Protein by Ammonium Sulfate Precipitation Approximately 300g of fresh spinach leaves were de-ribbed and dried, then homogenized for 1 minute in 200mL of buffer. From the homogenized solution, approximately 50ml was placed into a beaker, which was stirred on a stir plate while 10.90g of solid ammonium sulfate was slowly added to reach 37% saturation.
antibody purification ammonium sulfate precipitation
For the ammonium sulfate precipitation method, the concentrated sample was twice precipitated with 40% ammonium sulfate solution at pH 9.0. The yield and pu- rity of IgY were determined by ELISA and electrophore-sis.The yieldofIgY fromthecation exchangechromatog-raphy method was 30 to 40%, whereas that of the ammo-nium sulfate precipitation was 70 to 80%. The purity of IgY from the ammonium

Acetone precipitation of proteins Thermo Fisher Scientific
Ammonium sulfate, (NH 4) 2 SO 4, is often used for salting out because of its high solubility, which allows for solutions of very high ionic strength, low price, and availability of pure material.

Optimization of Isopropanol and Ammonium Sulfate
Ammonium sulfate precipitation of proteins Proteins are precipitated from aquaous solutions by dissolving ammonium sulfate into the protein solution. The following table shows the weight (g) of ammonium sulfate to be added to one litre of solution to produce a desired change in the concentration (% saturation) of ammonium sulfate.
