Target
Surfactant protein D (SP-D) is synthesized and secreted by lung epithelial cells. It belongs to group III of the family of C-type lectins and members of this group has overall structure consisting of multiple globular 'head' regions linked by triple-helical, collagen-like, strands. This group also includes SP-A and the serum proteins mannan-binding protein, conglutinin and collectin-43, all of which have been shown to bind to the C1q receptor found on a wide variety of cells. Both SP-D and SP-A have been shown to enhance oxygen radical production by alveolar macrophages. The serum concentration is 45 ng/ml in healthy individuals. (1)

Application

ELISA: HYB 238-04 reacts strongly with SP-A when tested in ELISA with SP-A directly coated onto the microtiter well.

WB: In Western blotting after SDS-PAGE HYB 238-04 reacts with reduced forms of SP-A and weaker with non-reduced forms. A dilution guideline of 1/1000 has proved successful. (2)

Paraffin-embedded sections of human lung immunostained with HYB 238-04. (1)

IHC: In immunohistochemical staining from paraffin embedded tissue samples, HYB 238-04 reacts specifically with human SP-A. Immunoreactivity is seen with alveolar type II cells, nonciliated bronchial cells and a subset of alveolar macrophages. No reactivity in samples from the pancreas, intestines, thymus, prostate gland or the peritoneal cavity lining cells. (1, 2)
