TEMED is a water-white colored liquid with a fishlike odor. Flash point 68°F. Less dense than water. Vapors heavier than air. It is molecule which allows rapid polymerization of polyacrylamide gels. In the presence of ammonium persulfate, TEMED is responsible for the formation of free radicals from persulfate, thereby initiating the acrylamide polymerization process. However, excess concentration of TEMED can result in abnormal separation patterns.
