Abstract
Antigen uptake by dendritic cells is the first key step towards induction of antigen-specific T-cell responses. This flow cytometry-based protocol describes the analysis of dendritic cell uptake of soluble antigens through two different mechanisms: non-specific macropinocytosis (using Lucifer Yelloy CH), and receptor-mediated endocytosis (using DQTM Ovalbumin). The protocol is generated based on data presented in Olivar et al. (2013).
