Species cross-reactivity is determined by western blot.
Applications Key: W=Western Blotting, IP=Immunoprecipitation, F=Flow Cytometry, IF-IC=Immunofluorescence (Immunocytochemistry),
Specificity / Sensitivity
MUC1 (D9O8K) XP® Rabbit mAb detects endogenous levels of total MUC1 protein. Because this protein is heavily glycosylated, multiple bands or a smear may result from western blot analysis using this antibody.
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues near the amino terminus of human MUC1 protein.
Confocal immunofluorescent analysis of ZR-75-1 (positive, left) and HCT 116 (negative, right) cells using MUC1 (D9O8K) XP® Rabbit mAb (green). Blue pseudocolor = DRAQ5® #4084 (fluorescent DNA dye).
Flow cytometric analysis of HCT 116 (blue) and ZR-75-1 (green) using MUC1 (D9O8K) XP® Rabbit mAb. Anti-rabbit IgG (H+L), F(ab')2 Fragment (Alexa Fluor® 488 Conjugate) #4412 was used as a secondary antibody.
Mucins represent a family of glycoproteins characterized by repeat domains and dense O-glycosylation (1). MUC1 (or mucin 1) is aberrantly overexpressed in most human carcinomas. Increased expression of MUC1 in carcinomas reduces cell-cell and cell-ECM interactions. MUC1 is cleaved proteolytically, and the large ectodomain can remain associated with the small 25 kDa carboxy-terminal domain that contains a transmembrane segment and a cytoplasmic tail of 72 residues (1). MUC1 interacts with ErbB family receptors and potentiates ERK1/2 activation (2). MUC1 also interacts with β-catenin, which is regulated by GSK-3β, PKCγ and Src through phosphorylation at Ser44, Thr41 and Tyr46 of MUC1 cytoplasmic tail (3-5). Overexpression of MUC1 potentiates transformation (6), and attenuates stress-induced apoptosis through the Akt or p53 pathways (7,8).
