Immunophenotyping, Part I: Instrument Calibration and Reagent Qualification for Immunophenotyping Analysis of Human Peripheral Blood Mononuclear Cell Cultures.

ABSTRACT

Nanoparticles are increasingly used in biomedical applications to influence the way the immune system reacts to tumors and infectious disease-causing agents. Nanoparticles not-intended for immunomodulation can also influence immune responses by affecting immune cell subsets' viability and/or activity. While immunophenotyping is commonly used to assess the effects of drugs and nanoparticles on immune cell subsets, no standardized approach exists due to the breadth of available cell models and instrumentation. In this chapter, we describe a protocol for flow cytometer calibration and reagent qualification prior to its use in the immunophenotyping experiment. The strategies described herein can be adapted to other instruments. The subsequent chapter-immunophenotyping part II (Chap. 25 )-provides detailed instructions for applying this methodology to analyze nanoparticle effects on subsets of immune cells present in peripheral blood.
