To prepare a 10% (w/v) solution: Dissolve 1 g ammonium persulfate in 10 mL of H 2 O and store at 4°C. Ammonium persulfate decays slowly in solution, so replace the stock solution every 2-3 wk. Ammonium persulfate is used as a catalyst for the copolymerization of acrylamide and bisacrylamide gels.
Preparation Add ~80% of the final volume of dH2O to a sterile media bottle. Ensure you have a volumetric flask measuring your desired final volume. Adjust the final volume and molar concentration in the table above and add the calculated amount of …
Once the total volume of ammonium sulfate is added, move beaker to 4°C for 6 hours or overnight. Transfer to conical tube and centrifuge the precipitate at 3000g for 30 minutes. Carefully remove and discard supernatant. Invert conical tube and drain well. For serum or ascites, resuspend pellet in 30%-50% of the starting volume in 1XPBS.
Ammonium sulfate decomposes upon heating above 250 °C, first forming ammonium bisulfate. Heating at higher temperatures results in decomposition into ammonia, nitrogen, sulfur dioxide, and water. As a salt of a strong acid (H 2 SO 4 ) and weak base (NH 3 ), its solution is acidic ; pH of 0.1 M solution is 5.5.
Preparation of ammonium sulfate ... sulfuric acid into an evaporating basin. 2. Wash the measuring cylinder and then add about 25cm. 3. ... check with indicator paper to see if the pH has reached 7. Add further 13cm amounts of ammonia solution if necessary, checking the pH after each addition, until the pH is 7 or above. 3. Put the evaporating ...
Addition of ammonium sulfate acidifies the solution so use at least a 50 mM HEPES or Tris buffer etc., 5mM EDTA can also be included. Add solid ammonium sulfate slowly with …
· How do you use ammonia sulphate? A traditional fertiliser, Sulphate of Ammonia should be applied evenly at the recommended rate and hoed into the top surface of the soil. If the soil is dry, it should be well watered in. Sulphate of Ammonia should not be left on leaves or stems, it should be lightly brushed off onto the surrounding growing media.

Prepare 800 mL of distilled water in a suitable container. Add 761 g of ammonium sulfate to the solution. Dissolve with stirring and gentle heating. Cool to room temperature and adjust the pH to 7 (with NH4OH or an acid such as HCl). If excess is to be stored, sterilize the solution by filtering through a 0.2-µm filter and store at 4°C.
· Ammonium sulfate is hygroscopic, which means it absorbs moisture from the air, so be sure to keep the bag tightly closed. Applying ammonium sulfate. As with any soil treatment, read the label and follow the directions. Seriously. When applying ammonium sulfate to your lawn or garden, be sure to water or work it into the soil right away.

· 70.6 g/100 mL (0 °C) and. 103.8 g/100 mL (100 °C) and the protocol says I need use 85% ammonium sulphate to dissovle some reagents. So I think it is supposed 85g can be dissolved in some quantity of water (which makes the total volume to 100ml). But anyway, I found I could not make it out. -Drlongwood-.
