Product Description
Paraformaldehyde solution is a neutral fixative solution used to fix tissues and cells in immunohistochemistry and immunocytochemistry protocols. Often stabilized in a phosphate buffer for delivery, this reagent actively cross-links proteins and DNA, immobilizing cellular components and maintaining the integrity of cell morphology. This reagent supports the accurate visualization of cells and tissues under a microscope, ensuring that researchers can observe fine details without degradation.
