Immunocytochemistry/ Immunofluorescence: Rabbit MUC1 mAb (Mc5) - Chimeric [NBP3-21451] - Immunofluorescence analysis of paraformaldehyde fixed MCF7 cells permeabilized with 0.15% Triton and stained with the chimeric mouse IgG1 version of Mc5 at 10 ug/ml for1h followed by Alexa Fluor® 488 secondary antibody (2 ug/ml), showing membrane staining. The nuclear stain is DAPI (blue). Panels show from left-right, top-bottom DAPI, merged channels and an isotype control. The isotype control was stained with an anti-unknown specificity antibody followed by Alexa Fluor® 488 secondary antibody.Western Blot: Rabbit MUC1 mAb (Mc5) - Chimeric [NBP3-21451] -
Western Blot: Rabbit MUC1 mAb (Mc5) - Chimeric [NBP3-21451] - MCF7 cell lysate (35µg protein in RIPA buffer) was resolved on a 10% SDS PAGE gel and blots probed with the chimeric rabbit IgG version of Mc5 at 2 µg/ml before detection using an anti-rabbit secondary antibody. A primary incubation of 1h was used and protein was detected by chemiluminescence. The expected running size for unmodified breast epithelial mucin is 122.1kDa, but this protein is heavily glycosylated and lipidated at several positions leading to the observed running size.Applications for MUC1 Antibody (Mc5) - Chimeric

Application Notes
In an attempt to develop a reliable way to detect breast cancer, immunoprecipitation was preformed on NPGP from HMFG using the mouse version of this antibody bound to Sepharose 4B. Furthermore, this antibody was tested in an radioimunnology experiment on NPGP using the mouse version of this antibody (Ceriani et al, 1992; pmid:1377884). The epitope of this antibody was mapped by ELISA using small peptides - the murine version of this antibody was used (Petrakou et al, 1998 ; pmid:9422085). This antibody was used to identify cells expressing the MUC1 protein. This was accomplished by using the mouse version of this antibody on cell lysates of cell transfected with the MUC1 protein in a western blot analysis (Rubinstein et al, 2006; pmid:17145869). To compare the diagnostic usefulness of different antibodies, the mouse version of this antibody was used for immunohistochemistry on cell pellets from pleural fluid specimens (Creaney et al, 2008; pmid:18454162). While developing an antibody against the alpha/beta junction of MUC1 the mouse version of this antibody was used for western blot on the MUC1 protein (Rubinstein et al, 2008; pmid:18821582). While assesing a panel of 56 anti MUC1 antibodies for their ability to detect cancer the mouse version of this antibody was used for an immunoradiometric assay on a serum made from sera from 10 different patients with breast, ovarian or colon cancer (Norum et al, 1998; pmid:9422099). To more accurately determine the epitope of this antibody, an ELISA was preformed using the murine version of this antibody on different small pepetides from the MUC1 protein (Karsten et al, 2004; pmid:15115750).

Background: MUC-1
Overexpression of mucins, including MUC1, is a feature of many epithelial cancers (1,3,5,6). The presence of truncated glycan structures called tumor-associated carbohydrate antigens (TACAs) on MUC1 play a role in cancer progression and a loss of apical-basal polarity (5). Carbohydrate-binding partners called lectins are the primary binding partners of TACAs that give rise to the pro-tumor microenvironment and metastasis (5). Given this unique feature, TACAs are a potential target for cancer immunotherapies (5). There are a number of vaccines, drugs, and antibodies targeting MUC1 for treatment of a variety of cancers including breast, lung, and prostate (6). In addition to a role in cancer progression, MUC1, and specifically the CT portion, has been shown to have a positive, anti-inflammatory role in a variety of lung and airway infections (7).
