蛋白结构(Molecular Characterization)

Online(Leu 1036 - Gly 1155) P15941-1

This protein carries a polyhistidine tag at the C-terminus. The mature form of Mucin-1 is a non-covalent heterodimeric complex with the proteolytically cleaved partial α and partial β chain. Each partial α and partial β chain has a calculated MW of 7.2 kDa (partial α chain) and 8.2 kDa (partial β chain). The protein migrates as 13-15 kDa (partial α chain) and 10 kDa (partial β chain) under reducing (R) condition (SDS-PAGE) due to glycosylation.

内毒素(Endotoxin)

Less than 1.0 EU per μg by the LAL method.

纯度(Purity)

>90% as determined by SDS-PAGE.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

活性(Bioactivity)-ELISA

Biotinylated Human ELISA

Immobilized Human Mucin-1 (1036-1155), His Tag (Cat. No. MU1-H52H5) at 1 μg/mL (100 μL/well) can bind Anti-Mucin-1 Antibody, Mouse IgG1 with a linear range of 0.2-6 ng/mL (QC tested).

Protocol

活性(Bioactivity)-FACS

Biotinylated Human FACS

2e5 of anti-Mucin-1 CAR-293 were stained with 100 μL of 0.1 μg/mL of Human Mucin-1, His Tag (Cat. No. MU1-H52H5) and negative control protein respectively, washed and then followed by PE anti-His Tag antibody and analyzed with FACS (Routinely tested).

背景(Background)

Mucin-1 (MUC1) is also known as Tumor-associated epithelial membrane antigen (EMA), Polymorphic epithelial mucin (PEM), Peanut-reactive urinary mucin (PUM), PEMT, Krebs von den Lungen-6 (KL-6), CD antigen CD227, Episialin, H23AG. MUC1 is a glycoprotein with extensive O-linked glycosylation of its extracellular domain. Mucins line the apical surface of epithelial cells in the lungs, stomach, intestines, eyes and several other organs. Mucins protect the body from infection by pathogen binding to oligosaccharides in the extracellular domain, preventing the pathogen from reaching the cell surface. Except protective function by binding to pathogens, MUC1 also functions in a cell signaling capacity. Overexpression of MUC1 is often associated with colon, breast, ovarian, lung and pancreatic cancers.
