Species:MouseImmunogen:Delipidated extract of human milk fat globule membranesClone:E29Isotype:IgG2a, kappaSpecies Reactivity:Human. Reacts moderately with Pig and Dog. Others not known.Positive Control:MCF-7 or MDA-231 cells. Breast or colon carcinoma.Specificity:In Western blotting, this antibody recognizes proteins in a MW range of 265-400kDa, identified as different glycoforms of MUC1. This antibody reacts with the DTRP epitope within the tandem repeats. In immunohistochemical assays, it superbly stains routine formalin/paraffin carcinoma tissues. An antibody to MUC1 is useful as a pan-epithelial marker for detecting early metastatic loci of carcinoma in bone marrow or liver. PolyTek，抗兔聚合HRP已开发，具有成本效益，可提供最清洁，最一致的染色。该系统基于聚合的过氧化物酶标记，该标记从等式中消除了生物素，从而消除了背景染色的主要原因。
