4% Paraformaldehyde Solution with Picric Acid in 1xPBS

The paraformaldehyde (PFA)-Picric Acid Solution in PBS (Bouin’s Fixative) is a high-quality, methanol-free solution formulated in PBS which contains 4% PFA, and picric acid. This fixative has been proven to preserve generally better morphology and antigenicity compared to the phosphate-buffered 4% paraformaldehyde. It can be used for tissue or cell fixative in IHC and ISH and reversible amine-crosslinking agent for protein and nucleic acid tissue samples.
