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