Detection of Mouse PLUNC by Western Blot. Western blot shows lysates of mouse lung tissue. PVDF membrane was probed with 1 µg/mL of Sheep Anti-Mouse PLUNC Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4274) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for PLUNC at approximately 30kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.
PLUNC in Mouse Embryo. PLUNC was detected in immersion fixed frozen sections of mouse embryo nose (13 d.p.c.) using Sheep Anti-Mouse PLUNC Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4274) at 1.7 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Sheep HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS019) and counterstained with hematoxylin (blue). Specific staining was localized to olfactory epithelium. View our protocol for Chromogenic IHC Staining of Frozen Tissue Sections.

PLUNC (Palate, lung, and nasal epithelium clone; also SPLUNC1) is a 25-30 kDa member of the PLUNC family, BPI/PLUNC/LBP superfamily of proteins. PLUNC is a secreted glycoprotein that is expressed by both adult and embryonic respiratory epithelium in the nose, trachea and bronchi/primary bronchioles. It serves as a natural antibacterial polypeptide in the respiratory system. Mature mouse PLUNC is 259 amino acids (aa) in length. It contains four, six-amino acid repeats (GxxLPL) over aa 23-52. There is reportedly one splice variant that shows a 28 aa substitution for the C-terminal 45 amino acids (aa 234-278). Over aa 59-278, mouse PLUNC shares 91% and 75% aa identity with rat and human PLUNC, respectively.
