  • Introduction to Polyacrylamide Gels | LSR | Bio-Rad

    Polyacrylamide (PAM) is a commercially relevant cationic polymer utilized mainly for water treatment due to its high efficiency and rapid dissolution. Being a cationic polymer, PAM can increase the settling rate of bacterial floc and improve the capture of dispersed bacterial cells, suspended solids, and cell fragments; therefore, one of its largest uses is to flocculate solids in a liquid.
