The presentation of lipid antigens to T cells is mediated by the CD1 proteins. Purified functional CD1/lipid complexes are valuable tools to investigate such immune processes. Here, we describe how these complexes can be prepared in vitro, how they can be purified by chromatofocusing and how to control their antigen-loading status by isoelectric focusing.
