- Add dH20 to a Falcon tube or other container suitable for the volume.
- Add 1 g of ammonium persulfate per 10 mL of water.
Are ammonium sulfate and ammonium persulfate the same?
Ammonium persulfate is used in the oxidative polymerization of aniline, and ammonium sulfate is a by-product of the polymerization reaction.you cannot replace it. Ammonium sulfate is used in combination with ammonium persulfate.
What is the role of ammonium persulfate?
Thermo Scientific Pierce Ammonium Persulfate (APS) is an oxidizing agent that TEMED-catalyzed polymerization of acrylamide and bis-acrylamide to prepare polyacrylamide gel electrophoresis.
Is ammonium persulfate toxic?

Is Ammonium Sulfate a Good Fertilizer?
as a water soluble fertilizer, Ammonium sulfate is widely used in crop production because it provides effective nitrogen and readily available sulfur that aids plant growth. This fertilizer is essential for maintaining healthy soil and vigorous crop growth by increasing the general value of alkaline soils.
Which products contain ammonium persulfate?

Where do you store ammonium persulfate?
Storage: Store at room temperature (15-30 °C),dry. Ammonium persulfate is a strong oxidant. It is a free radical initiator. Ammonium persulfate is a polymerization catalyst used with TEMED for polyacrylamide gel formation.
Why add TEMED at the end?
When making gel solutions, TEMED must be added last because it will immediately start responding to APS, and catalyzes the polymerization of acrylamide and bisacrylamide. Therefore, the following mixing and pouring steps must be completed as soon as possible.
What is a concentrated gel?
stacking gel is low concentration polyacrylamide gel In the SDS-PAGE technique, it is placed on top of a more concentrated separating gel (separating gel). Stacking gels are used to improve the resolution of electrophoresis.
