Biolegend, 355601, Purified anti-human CD227 (MUC-1) Antibody, 25μg

Mucin-1 (MUC-1), cell surface associated or polymorphic epithelia mucin, is a 500-1000 kD proteoglycan expressed by activated T cells, mucosal epithelial cells, and aberrantly expressed on most breast cancers.  In normal cells, CD227 is heavily glycosylated, whereas in cancerous cells, the glycosylation is incomplete and premature sialation is also observed.  The protein is anchored to the apical surface of the epithelial cell and functions as a lubricant to keep the cell hydrated and to protect against pathogens.  It can also function as a signaling molecule by forming a MUC-1/SOS1/GrB2 complex.  MUC-1 can interact with cancer antigens such as Her2/neu.
25μg
Verified Reactivity: Human
Antibody Type: Monoclonal
Host Species: Mouse
Immunogen: Jurkat cells transfected with MUC1
Formulation: Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide.
Preparation: The antibody was purified by affinity chromatography.
Concentration: 0.5 mg/mL
Storage & Handling: The antibody solution should be stored undiluted between 2°C and 8°C.
Application: FC - Quality tested ICC, IHC-P - Verified
Recommended Usage: Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤ 1.0 µg per million cells in 100 µL volume. For immunohistochemistry on formalin-fixed paraffin-embedded tissue sections, a concentration range of 1 - 10 µg/mL is suggested. It is recommended that the reagent be titrated for optimal performance for each application.
Application Notes: This clone shows stronger binding to the glycosylated compared to the non-glycosylated peptide1.
