Used in cell biology and tissue engineering to gently break down animal tissues into single cells or small cell clusters for primary cell culture. The kit typically contains enzymes like collagenase and dispase, which digest extracellular matrix proteins, allowing efficient cell isolation without damaging cell membranes. Commonly applied in research involving stem cells, cancer biology, and regenerative medicine where high cell viability and yield are essential. Also utilized in preparing cells for flow cytometry, cryopreservation, and in vivo transplantation studies.
