Easy to Handle

Polyacrylamide gel is a polymer resulting from the radical polymerization bonding of acrylamide and N, N’-Methylenebisacrylamide (Bis), which serves as a crosslinking agent. Acrylamide assumes a linear structure, and the crosslinking agent functions as a bridge, culminating in a polymer (gel) with a net structure. The pore size of the gel increases with lower concentrations, facilitating the separation of high molecular weight proteins. However, the solubility of Bis is limited, leading to non-uniform gel formation characterized by clumps. Such non-uniform gels exhibit reduced strength and are prone to tearing, posing handling challenges. Addressing this, ATTO has successfully developed a uniform gel at low concentrations utilizing a novel crosslinking agent boasting higher solubility and longer bonding arms compared to Bis. This innovation not only enhances gel strength, with tensile fracture stress approximately 1.7 times higher than Bis but also facilitates smoother sample entry into the gel's net structure due to its larger pore size, thereby significantly improving separability.
