Frozen tissue

Frozen tissue refers to biological samples, like organs or biopsies, that are rapidly frozen to preserve their cellular structure and components. Freezing halts biological activity and prevents decomposition, allowing scientists and doctors to analyze the tissue later. This process is essential for accurate testing, research, and diagnosis, as it maintains the tissue's integrity for microscopic examination or molecular analysis. Typically, tissues are frozen using specialized equipment at very low temperatures, often with liquid nitrogen, ensuring they remain unaltered until needed for study or medical evaluation.
