Background:
During Ficoll density gradient centrifugation, granulocytes (neutrophils, basophils, eosinophils) form a layer separate from
peripheral blood mononuclear cells (PBMCs). The granulocyte layer is directly above the red blood cells. Thus, when this layer is collected, red blood cells will be present. After isolating this layer, RayBiotech will lyse the red blood cells. The number of granulocytes obtained per patient will vary. All cells will be provided to customer; the number of provided cells cannot be guaranteed.
Sample Type:
Granulocytes (treated with red blood cell lysis buffer)
Format:
Frozen with 10% DMSO
Shipping temperature:
Shipped on dry ice
Storage temperature:
Store in liquid nitrogen vapor phase
Biosafety Level:
2
Note: While the patients were confirmed to have COVID-19 via a test detecting either SARS-CoV-2 virus or viral proteins using a nasopharyngeal swab, these samples have not been tested for the presence of virus or any other diseases and should be assumed infectious.
