MUC5AC and neoplasm: This also showed cytoplasmic or membranous expression of MUC-1, (Fig. 8) (Abcam, Ab696-250, 1:100) predominantly in the deeper aspect of the tumour, but did not stain for MUC-2 (Novocastra, NCL MUC2, 1:100), MUC5 (Novocastra, NCL MUC5, 1:100) or MUC-6 (Novocastra, NCL MUC6, 1:100).
