  • Introduction to Polyacrylamide Gels | LSR | Bio-Rad

    Polyacrylamide (PAM) is a type of hydrogel consisting of a loosely cross-linked acrylamide structure that can hold large amount of water. Due to their high water content, polyacrylamide is also highly amenable for use as biomaterial that can be in contact with tissue or biological fluids as implants, soft contact lenses, and drug delivery particle systems.
