Abstract

Flow cytometry is a powerful analytical technique. However, it requires time-consuming, multi-step sample procedure. A new protocol was developed to perform extracellular staining and red blood cell lysis in one step, using dry antibodies. Common markers of white blood cells as well as sepsis biomarkers were tested as a model for modulated antigen expression.
