About
Polysciences’ Formalin Free Fixatives collection offers advanced fixation reagents that avoid traditional formaldehyde crosslinking, thereby enhancing molecular recovery of DNA, RNA and proteins while maintaining tissue morphology. Products such as the HOPE® Fixative System provide fully formalin-free protocols for paraffin-embedded tissues, facilitating immunohistochemistry, in situ hybridization, PCR and RT-PCR without the drawbacks of classical formalin fixation.
