Product Description

The 4% Paraformaldehyde solution serves as a reliable tissue and cell fixative formulated in phosphate buffer for optimal stability. By forming covalent cross-links between proteins and DNA, it locks cellular structures in place while preserving authentic morphology for microscopic evaluation. This fixative is particularly suited for high‑resolution imaging and immunolabeling studies that require structural preservation and antigen integrity. Its balanced composition promotes consistent fixation, preventing degradation and morphological alteration during imaging workflows.
