Trehalose is a non‑permeating cryoprotectant that stabilizes membranes, protects proteins, and reduces ice formation. This article explains its mechanisms and applications in cryobiology.

The glass transition temperature (Tg) marks the point where biological solutions become glass‑like and molecular motion stops. This article explains Tg, its mechanism, and its importance in cryopreservation.

Cryoprotective agents (CPAs) protect biological materials during freezing and thawing by reducing ice formation, osmotic injury, and membrane damage. This article explains CPA types, mechanisms, toxicity, and their role in modern cryopreservation.

Cryopreservation is a vital technology that preserves biological materials at ultra‑low temperatures, supporting medicine, research, agriculture, biotechnology, and wildlife conservation. This article explores its diverse applications and growing importance in science and global biodiversity protection.

Cryopreservation enables long‑term storage of living cells and tissues at ultra‑low temperatures by halting biological time. This article explains freezing damage, cryoprotective agents, slow freezing, vitrification, and natural freeze tolerance.

This protocol describes the revival process of cryopreserved adherent cells. The revival process involves rapid thawing of cryopreserved cells followed by removal of freezing medium which contains cryoprotectant, in this case, DMSO. The freezing medium can be removed immediately just after thawing the cells by centrifugation. Alternatively, cells are allowed to adhere to the culture dish followed by washing and addition of fresh growth medium.

Cryopreservation is an efficient way to preserve cells at ultra-low temperatures (below -135°C) which stops all physiological processes and biological aging. It is a routinely used technique in all cell culture laboratories.
