Natural Killer cells (NK cells) constitute a lymphocytic subset of the immune system and play a crucial role in immunological surveillance and host defence. Their significance spans across various areas such as bone marrow transplantation, cancer, pregnancy, autoimmune diseases, viral infections, and increasingly in adaptive immunity.
- Purity >90% by flow cytometry
- Test negative for Hepatitis B and C, HIV 1/2, HTLV-I/II, HIV-1/HCV/HBV
- Cryopreserved in CryoStor® CS10 media
The common identification of NK cells is achieved through the surface marker CD56. These cells are isolated using negative or positive selection through immunomagnetic cell separation procedures.
Cells were collected from from a healthy human donors using permission forms and procedures that have been approved by the Institutional Review Board (IRB).
Storage: For prolonged cell preservation or resuscitation, it is recommended to prepare the cells for extended storage in the vapor phase of liquid nitrogen. Storage of cells in the liquid phase of nitrogen is strongly discouraged to prevent potential cross-contamination risks when removing from storage. Long-term storage under −175 °C and for short-term storage, about one or two weeks at −80 °C is permitted, but it is recommended to minimise this duration to ensure optimal stability. Thawed samples should be used immediately and not stored.
