Background
Muc1 is a heavily O-glycosylated transmembrane protein expressed on most secretory epithelium, including mammary gland and some hematopoietic cells. It is expressed abundantly in lactating mammary glands and overexpressed in >90% breast carcinomas and metastases. In normal mammary gland it is expressed in apical surface of glandular epithelium. In breast cancer Muc1 is overexpressed; is underglycosylated and the apical localization is lost. Muc1 is transcribed as a larger precursor which is cleaved to form a larger mucin like subunit (265-400kDa) and a smaller subunit (14-28kDa) noncovalently associated with each other. Transgenic Muc1 has been shown to associate with all four erbB receptors and localize with erbB1 (EGFR) in lactating glands1. Muc1 can act as a ligand for ICAM-1 on HUVEC cells; it can bind -catenin, GSK3 and it associates with Grb2-SOS upon phosphorylation.

Type
Monoclonal Antibody
Source
Hybridoma produced by the fusion of splenocytes from BALB/c mice immunized with a Muc1 60mer tandem repeat NH2-(VTSAPDTRPAPGSTAPPAHG)3-COOH and mouse myeloma SP2 cells.
Applications
IHC (frozen and paraffin), ELISA, WB
Field of Research
Signal Transduction, Cell adhesion
Purification Method
Protein A/G Chromatography
Assay Principle
Antibody can be used for immunohistochemistry on frozen and paraffin embedded tissues, ELISA and Western blotting. Optimal concentration should be evaluated by serial dilutions. Antibody can only detect Muc1 if the threonine residue of the PDTRPAP of the tandem repeat region is non-glycosylated4.
Stability
See expiration date on vial
Concentration
See vial for Concentration
Form
Provided as solution in phosphate buffered saline with 0,08% sodium azide
Precautions
This product is intended FOR RESEARCH USE ONLY, and FOR TESTS IN VITRO, not for use in diagnostic or therapeutic procedures involving Humans or animals.
