Granulocyte layer from 50 cc of whole blood (1 patient)
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.
Granulocytes (treated with red blood cell lysis buffer)
Frozen with 10% DMSO
Shipped on dry ice
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.
