Description	4% Paraformaldehyde solution in PBS is a ready-to-use solution for sample preparation and fixing cells for immunohistochemistry (IHC).
Background	Paraformaldehyde (PFA) is the polymerization product of formaldehyde with a typical degree of polymerization of 8–100 units. Paraformaldehyde is not a fixative itself; it must be depolymerized to formaldehyde in solution. In cell culture, a typical formaldehyde fixing procedure would involve using a 4% formaldehyde solution in phosphate buffered saline (PBS) on ice for 10 minutes. Fixing ensures that sample cell structures stay intact and that antigens are immobilized, while ideally still permitting unfettered access of antibodies to target antigens.
Storage	Store at -20˚C for one year from date of receipt. After reconstitution, at 4˚C for one month. It can also be aliquotted and stored frozen at -20˚C for six months. Avoid repeated freeze-thaw cycles.. Shipped in room temperature.
