  • Product Description

    Paraformaldehyde is one of the most commonly used fixatives in immunohistochemistry (IHC) and immunocytochemistry (ICC). This mild fixative effectively preserves both antigenicity and fine structural details, making it well suited for the long-term preservation of tissue specimens and cell smears, and ideally suited for light microscopy–based immunochemical studies of tissues and cells.

    This product is an enzyme‑free formulation prepared with DEPC‑treated water and can be used directly in cell and molecular biology experiments; it is a 4% paraformaldehyde solution in PBS, suitable for direct use in tissue and cell fixation.
