Recognizes the glycosylated form of MUC1. Similar results were also obtained with an mAb that recognizes the unglycosylated form of MUC1 (Ma552)
Wang et al.[94] using the Ma695 mAb reported a similar observation that MUC1+ breast cancers were more likely to be ER+ and of a lower grade than MUC1- tumors.
Expression was significantly downregulated in tumor tissue compared to adjacent normal breast tissue by IB.
