Induction of a humoral immune response after immunization of two Lama glama with CD1d‐transfected C1R cells. Reactivity of differentially diluted pre‐immune (●), as well as post‐immune day 28 (■) and day 43 (▲) sera against whole C1R‐CD1d cells as detected by flow cytometry after sequential incubation of C1R‐CD1d cells with llama sera, rabbit‐anti‐llama sera and FITC‐labelled swine anti‐rabbit antibody. Data reflect mean fluorescence intensity (MFI) as determined in two individual llamas (a and b).
