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 88 ng/ml in healthy individuals. (1)

Application

ELISA: HYB 245-01 can be used for ELISA with Ca++ present in the buffer.

WB: In Western blotting after SDS-PAGE HYB 245-01 reacts strongly with SP-D, both in reduced and non-reduced forms. In Western blotting a dilution guideline of 1/20.000 has proved successful. (2, 3)

IHC: In immunohistochemical staining on paraffin embedded tissues, HYB 245-01 reacts specifically with SP-D. Immunoreactivity can be found in epithelial cells of the lung, skin, small intestine, esophagus, gall-bladder, kidney and urinary bladder. (1, 2, 3)
