    BT474 breast cancer cell line was stained with anti-human CD227, detected with anti-mouse DyLight™ 649, and nuclear counterstained with DAPI. Images were acquired with a TE300 fluorescence microscope with a 20x objective. Data provided by: Er Liu and John Nolan, La Jolla Bioengineering Institute

    IHC staining using purified anti-MUC1 antibody (clone 16A) on formalin-fixed paraffin-embedded human colon tissue. Following antigen retrieval using 1X Tris-EDTA, the tissue was incubated with 10 µg/mL of antibody overnight at 4°C, followed by incubation with 2.5 µg/mL of Alexa Fluor® 647 goat anti-mouse IgG antibody (Cat. No. 405322) for one hour at room temperature. Nuclei were counterstained with DAPI (blue) (Cat. No. 422801), and the slide was mounted with ProLong™ Gold Antifade Mountant. The images above (left: secondary only control, right: Clone 16A, 10 µg/mL) were captured with a 40X objective. Scalebar = 50 µM.

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.

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.
