Tetramethylethylenediamine (TMEDA or TEMED) is a chemical compound with the formula (CH3)2NCH2CH2N(CH3)2. This species is derived from ethylenediamine by replacement of the four amine hydrogens with four methyl groups. It is a colorless liquid, although old samples often appear yellow. Its odor is similar to that of rotting fish. WebTEMED, a free radical stabilizer, is generally included to promote polymerization. in essence, TEMED catalyzes the polymerization of acrylamide and bisacrylamide monomers. what is sodium dodecyl sulfate (SDS)? an amphipathic detergent precast polyacrylamide gels have various acrylamide concentrations and gradients
