Product Format frozen 1.0 mL
Images PCS-800-019 Application Data
Comments CD56+ Natural killer (NK) cells are the major effectors of the innate immune system and are important in host defense, cancer, and autoimmunity.
CD56+ Natural Killer Cells are isolated from mononuclear cells by negative selection using immunomagnetic cell separation procedures.
ATCC CD56+ Natural Killer cells are tested by flow cytometry for the following surface markers:  
  • CD45+: ≥ 90% 
  • CD56+: ≥ 90% 
  • CD56+CD3-: Report results 
  • CD56+CD16+: Report results
Complete Growth Medium Natural Killer Cells have a limited lifespan in culture and should be thawed immediately and only prior to their intended use in application specific media. ATCC recommends thawing them in RPMI-1640 (ATCC 30-2001). ATCC does not recommend maintaining Natural Killer Cells in culture in the absence of application-specific growth factors.
