Scientific Data Images for Human CEACAM‑7 Antibody

Detection of CEACAM-7 antibody in HEK293 Human Cell Line Transfected with Human CEACAM-7 and eGFP antibody by Flow Cytometry.

Detection of CEACAM‑7 in HEK293 Human Cell Line Transfected with Human CEACAM-7 and eGFP by Flow Cytometry.

HEK293 human embryonic kidney cell line transfected with human CEACAM-7 and eGFP was stained with either (A) Mouse Anti-Human CEACAM-7 Monoclonal Antibody (Catalog # MAB44781) or (B) Mouse IgG1 Isotype Control (Catalog # MAB002) followed by APC-conjugated Anti-Mouse IgG Secondary Antibody(Catalog # F0101B).

CEACAM-7 antibody in Human Colon Cancer Tissue by Immunohistochemistry (IHC-P).

CEACAM‑7 in Human Colon Cancer Tissue.

CEACAM-7 was detected in immersion fixed paraffin-embedded sections of human colon cancer tissue using Mouse Anti-Human CEACAM-7 Monoclonal Antibody (Catalog # MAB44781) at 5 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Mouse IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC001). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm.

Human CEACAM-7 Antibody in ELISA Standard Curve.

Human CEACAM‑7 ELISA Standard Curve.

Recombinant Human CEACAM-7 protein was serially diluted 2-fold and captured by Mouse Anti-Human CEACAM-7 Monoclonal Antibody (Catalog # MAB44782) coated on a Clear Polystyrene Microplate (Catalog # DY990). Mouse Anti-Human CEACAM-7 Monoclonal Antibody (Catalog # MAB44781) was biotinylated and incubated with the protein captured on the plate. Detection of the standard curve was achieved by incubating Streptavidin-HRP (Catalog # DY998) followed by Substrate Solution (Catalog # DY999) and stopping the enzymatic reaction with Stop Solution (Catalog # DY994).

Applications for Human CEACAM‑7 Antibody

Application
Recommended Usage

CyTOF-ready

Ready to be labeled using established conjugation methods. No BSA or other carrier proteins that could interfere with conjugation.

ELISA

This antibody functions as an ELISA detection antibody when paired with Mouse Anti-Human CEACAM‑7 Monoclonal Antibody (Catalog # MAB44782).

This product is intended for assay development on various assay platforms requiring antibody pairs. We recommend the Human CEACAM-7 DuoSet ELISA Kit (Catalog # DY4478-05) for convenient development of a sandwich ELISA.

Background: CEACAM-7

Carcinoembryonic antigen-related cell adhesion molecule 7 (CEACAM-7), also known as CGM2, is an approximately 40 kDa GPI-anchored glycoprotein in the CEACAM family of adhesion molecules (1). Mature human CEACAM-7 consists of two Ig-like domains followed by the GPI anchor (2). Alternative splicing generates a short isoform that lacks the second Ig-like domain. CEACAM-7 is preferentially expressed on the luminal surface of epithelial cells near the mouth of colonic crypts and on pancreatic ductal epithelial cells (3, 4). It is down-regulated during colorectal adenoma progression (2-6) but can be up-regulated during the development of gastric carcinoma (7). R&D Systems in-house testing indicates that CEACAM-7 binds to CEACAM-1, consistent with the heterophilic interaction of CEACAM-1 with other CEACAM family members (1, 8, 9).
