CEBPZ and ocular melanoma: Western immuno-blotting demonstrated specificity of the murine immune responses (Fig 4A): antisera to rCBF-saline, rCBF-Al(OH)3, rCBF-liposomes ± MPLA and rCBF-Zw 3–14 micelles ± MPLA reacted with a single protein band of Mr ~29.5 kDa, which is consistent with homologous CBF protein in MC58 OM, whereas sera from sham-immunised mice were non-reactive.
