N,N′-Diallyl-L-tartardiamide (DATD) is a crosslinking agent for polyacrylamide gels, e.g., as used for SDS-PAGE.[1] Compared to bisacrylamide gels, DATD gels have a stronger interaction with glass, and therefore are used in applications where the polyacrylamide gel acts as a "plug" structural component at the bottom of a gel electrophoresis apparatus, thereby preventing a weak discontinuous gel from sliding out from or otherwise moving within the apparatus.[1][2] Unlike bisacrylamide-polyacrylamide gels, DATD-polyacrylamide gels can be conveniently dissolved using periodic acid due to the presence of viscinal diols in DATD.[3] DATD is the slowest polyacrylamide crosslinker tested,[4] and has can act as an inhibitor of polymerization at high concentrations.[4][5][6]
