Data Examples
Immunocytochemistry
BNP in BG01V Human Cells. BNP was detected in immersion fixed BG01V human embryonic stem cells using Rat Anti-Human Pro-BNP Monoclonal Antibody (Catalog # MAB36041) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Rat IgG Secondary Antibody (red; Catalog # NL013) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.
Immunohistochemistry
Pro-BNP in Human Heart.
Pro-BNP was detected in immersion fixed paraffin-embedded sections of human heart using 25 µg/mL Rat Anti-Human Pro-BNP Monoclonal Antibody (Catalog # MAB36041) overnight at 4 °C. Tissue was stained with the Anti-Rat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS017) and counterstained with hematoxylin (blue). Specific labeling was localized to endothelial cells in the vasculature. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

Background: BNP
Brain-type Natriuretic Peptide (BNP) is a nonglycosylated peptide that is produced predominantly by ventricular myocytes and belongs to the natriuretic peptide family. Proteolytic cleavage of the 12 kDa BNP precursor gives rise to N-terminal Pro‑BNP (NT-proBNP) and mature BNP. Plasma NT-proBNP is a marker for congestive heart failure, while mature BNP (aa 103‑134) promotes vasodilation and fluid and sodium excretion. Human BNP precursor shares 29% and 51% aa sequence identity with mouse and porcine BNP precursor, respectively.
  • Long Name:
    Brain Natriuretic Peptide
  • Entrez Gene IDs:
    4879 (Human); 18158 (Mouse); 25105 (Rat)
  • Alternate Names:
    BNF; BNP; brain type natriuretic peptide; Gamma-brain natriuretic peptide; natriuretic peptide B; natriuretic peptide precursor B; natriuretic peptides B; natriuretic protein; NPPB
