Scientific Data

Western Blot Detection of Human MUC-1 antibody by Western Blot. View Larger

Detection of Human MUC‑1 by Western Blot. Western blot shows lysates of human lung tissue. PVDF Membrane was probed with 2 µg/mL of Mouse Anti-Human MUC-1 Monoclonal Antibody (Catalog # MAB6298) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for MUC-1 at approximately 300 kDa (as indicated). This experiment was conducted under non-reducing conditions and using Immunoblot Buffer Group 1.

Flow Cytometry Detection of MUC-1 antibody in MCF-7 Human Cell Line antibody by Flow Cytometry. View Larger

Detection of MUC-1 in MCF‑7 Human Cell Line by Flow Cytometry. MCF-7 human breast cancer cell line was stained with Mouse Anti-Human MUC-1 Monoclonal Antibody (Catalog # MAB6298, filled histogram) or isotype control antibody (Catalog # MAB0041, open histogram), followed by Allophycocyanin-conjugated Anti-Mouse IgG F(ab')2Secondary Antibody (Catalog # F0101B).

Immunocytochemistry MUC-1 antibody in Capan-1 Human Cell Line by Immunocytochemistry (ICC). View Larger

MUC‑1 in Capan‑1 Human Cell Line. MUC-1 was detected in immersion fixed Capan-1 human pancreatic adenocarcinoma cell line using Mouse Anti-Human MUC-1 Monoclonal Antibody (Catalog # MAB6298) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to cell surfaces and cytoplasm. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

Immunohistochemistry MUC-1 antibody in Human Breast by Immunohistochemistry (IHC-P). View Larger

MUC‑1 in Human Breast. MUC-1 was detected in immersion fixed paraffin-embedded sections of human breast using Mouse Anti-Human MUC-1 Monoclonal Antibody (Catalog # MAB6298) at 15 µg/mL overnight at 4 °C. Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013). Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm of epithelial cells. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

Simple Western Detection of Human MUC-1 antibody by Simple Western<SUP>TM</SUP>. View Larger

Detection of Human MUC‑1 by Simple WesternTM. Simple Western lane view shows lysates of human lung tissue, loaded at 0.2 mg/mL. Specific bands were detected for MUC‑1 at approximately 300-500 kDa (as indicated) using 40 µg/mL of Mouse Anti-Human MUC‑1 Monoclonal Antibody (Catalog # MAB6298). This experiment was conducted under reducing conditions and using the 66-440 kDa separation system.

Immunocytochemistry/ Immunofluorescence Detection of Human MUC1 by Immunocytochemistry/Immunofluorescence View Larger

Detection of Human MUC1 by Immunocytochemistry/Immunofluorescence Co-localization of PAM4 antigen with MUC5AC by immunofluorescence staining(A) Mucin-expressing cell lines were stained with DAPI, hPAM4, and anti-MUC5AC (2-12M1 for Capan-1 and BxPC-3; 2-11M1 for HT-29 and MCF-7), then examined by immunofluorescence microcopy. (B) BxPC-3 and HT-29 cells were stained with DAPI, hPAM4, and alpha -MUC1. PAM4 antigen was shown to co-localize with MUC5AC, not MUC1.

Background: MUC-1

MUC-1 (Mucin-1; also PEM, PEMT, Episialin, tumor-associated mucin, and carcinoma associated mucin) is a 240-450 kDa type I transmembrane glycoprotein. Human MUC-1 is 1255 amino acids (aa) in length and contains a 23 aa signal sequence, a 1135 aa extracellular domain (ECD), a 23 aa transmembrane segment, and a 74 aa cytoplasmic tail. The ECD consists of degenerate tandem repeats and a tandem repeat region, which makes up the major portion of the protein. Potential O-glycosylation sites (serines and threonines) make up more than one-fourth of the amino acids. Splicing variants produce ten isoforms for human MUC-1. Human MUC-1 is 28% aa identical to mouse MUC-1.
