Product Overview

Natural Killer (NK) Cells

Product Description: Natural Killer (NK) cells are a lymphocyte of the immune system that play a crucial role in the immune system. They were first identified for their ability to target and destroy cancer cells and tumors without deliberate immunization.  They are conventionally characterized by the expression of CD56 cell surface marker and absence of CD3 marker. CD16 cell surface marker also plays a key role in the biology of NK cells by inducing release of cytokines and cytotoxic functions. 

Size: 5E6 and 10E6

Tissue Source: Leukopak

Cell Isolation: Cell isolation is performed on-site at our Gift of Life Center for Cell and Gene TherapyNK cells are positively isolated from leukopaks. Blood cells expressing CD56 maker are enriched from a leukopak using immunomagnetic beads that label the target cells, resulting in a purified NK cell population. Viability and purity post isolation are assessed by flow cytometry.

Cryopreservation and Storage: Cell products contain 10% DMSO to preserve cell viability and reduce loss during freezing. Cryopreserved products are stored in LN2 tanks and shipped on dry ice.

Thawing Instructions: Refer to our thawing protocol
