MUC-1 / PE / REA448
Product Details
| Description | Clone REA448 recognizes the human CD227 antigen, a single-pass type I membrane protein which is also known as mucin-1 (MUC-1), episialin, or epithelial membrane antigen (EMA). CD227 is a heterodimeric epithelial cell glycoprotein that is normally expressed at low levels on the apical surface of epithelial cells and on some hematopoietic cell lineages including subsets of T cells, B cells, monocytes, and dendritic cells. In most adenocarcinomas and in other inflammatory diseases of epithelial tissues, CD227 is overexpressed and loses the polarity of its expression. On normal epithelia, CD227 is extensively O-glycosylated with long branched glycans, whereas on tumor cells they are markedly hypoglycosylated with simpler and shorter glycan chains. Elevated levels of CD227 on the tumor have been associated with invasiveness and poor prognosis in colon, pancreas, breast, and bladder cancer. CD227 regulates the metabolite flux at multiple levels. Serving as a transcriptional co-activator, CD227 directly regulates expression of metabolic genes. By regulating receptor tyrosine kinase signaling, CD227 facilitates production of biosynthetic intermediates required for cell growth. CD227 also modulates the activity/stability of enzymes and transcription factors that directly regulate metabolic functions. | Additional information: Clone REA448 displays negligible binding to Fc receptors. | |

About MUC-1
This gene encodes a membrane-bound protein that is a member of the mucin family. Mucins are O-glycosylated proteins that play an essential role in forming protective mucous barriers on epithelial surfaces. These proteins also play a role in intracellular signaling. This protein is expressed on the apical surface of epithelial cells that line the mucosal surfaces of many different tissues including lung, breast stomach and pancreas. This protein is proteolytically cleaved into alpha and beta subunits that form a heterodimeric complex. The N-terminal alpha subunit functions in cell-adhesion and the C-terminal beta subunit is involved in cell signaling. Overexpression, aberrant intracellular localization, and changes in glycosylation of this protein have been associated with carcinomas. This gene is known to contain a highly polymorphic variable number tandem repeats (VNTR) domain. Alternate splicing results in multiple transcript variants.[provided by RefSeq, Feb 2011]

About PE
Phycoerythrin (PE, R-PE) is a red-emitting fluorescent protein-chromophore complex that can be excited the 488-nm blue, 532-nm green, or 561-nm yellow-green laser with increasing efficiency and captured with a 586/14 nm bandpass filter. PE has an excitation peak at 565 nm and an emission peak at 578 nm. PE is 240kD in size and has an extinction coefficient of ~2x10^6 which makes it one of the brightest fluorophores available and a potent donor upon which to build tandem fluorophores with longer Stoke's Shifts.
