This protocol describes a semi-automatic immunofluorescence (IF) assay for PD-L1 characterization and enumeration of CTCs in non-small cell lung cancer (NSCLC) patient samples. Immunology and Infection Neutrophil Isolation and Analysis to Determine their Role in Lymphoma Cell Sensitivity to Therapeutic Agents Taghreed Hirz1, Charles Dumontet1 1Immunity, Microenvironment, Virus, Cancer Research Center in Lyon Neutrophils are the most abundant type of white blood cells. The isolation of neutrophils from human blood by density gradient separation method and the differentiation of human promyelocytic (HL60) cells along the granulocytic pathway are described here; to test their role on sensitivity of lymphoma cells to anti-lymphoma agents.

This method constitutes a valuable approach to study the physiology of fresh primary normal/untransformed exocrine pancreatic cells.
