Natural killer (NK) cell growth factors and cytokines
Highly bioactive, animal-free growth factors and cytokines for NK cell culture.
Natural killer (NK) cells are a type of cytotoxic lymphocyte that plays a critical role in the innate immune system’s defense against infected and cancerous cells. Unlike T cells, which are part of the adaptive immune response, NK cells do not require prior activation to kill their targets. Instead, they can quickly identify and eliminate abnormal cells, including virus-infected cells and tumor cells. NK cells also play a role in regulating immune responses by interacting with other immune cells, such as dendritic cells and macrophages. They can modulate the activity of these cells through direct cell-cell contact or by secreting regulatory cytokines. Qkine proteins for Natural Killer Cells include IL-3, SCF and Flt3L.
Qkine robust animal-free manufacturing platform, along with rigorous quality control procedures, ensure that all our growth factors and cytokines are:
- animal origin-free (AOF) and carrier protein-free
- highly pure (>98%, by SDS-PAGE quantitative densitometry)
- highly bioactive (equally or more bioactive than other dominant suppliers) and come with our Bioactivity Guarantee
- highly reproducible with excellent lot-to-lot consistency
