What is cross linked polyacrylamide? Explained by FAQ Blog

Sodium polyacrylate is an example of a super-absorbing polymer. It is a cross-linked (network) polymer that contains sodium atoms. It absorbs water by a process called osmosis. Are polyacrylamide crystals toxic? Polyacrylamide is not toxic; however, it can eventually break down into acrylamide, which is a skin irritant and toxic to ingest.

Traditionally, cross-linked polyacrylamides and agarose have been utilized in the slab and tube format. Polyacrylamides when cross-linkedhave smaller pore sizesand are used for protein separations. The larger pore sizesof agarose gels are more suitable for DNA separation. Polyacrylamides yield very viscous gels.
