96% PFA Polyoxymethylene

Pfa polyoxymethylene 96% paraformaldehyde paraformaldehyde 96% is not a fixative; it must be depolymerized to formaldehyde in solution. In cell culture, a typical formaldehyde fixing procedure would involve using a 4% para-formaldehyde in phosphate buffered saline (pbs) on ice for 10 minutes.paraformaldehyde 92% is also used to crosslink proteins to dna, as used in chip (chromatin immuno precipitation) which is a technique to determine which part of dna that certain proteins are binding to.
