Clone Host Grade Applications
Monoclonal Mouse Affinity Purified E B IH
Surfactant protein A (SP-A) 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-D 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 45ng/ml in healthy individuals.
Catalog #S8400-08
ApplicationsSuitable for use in ELISA, Western Blot and Immunohistochemistry. Other applications not tested.
Recommended DilutionsWestern Blot: 1:1000
Immunohistochemistry: Paraffin-embedded sections
Optimal dilutions to be determined by the researcher.
Storage and StabilityMay be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 12 months after receipt. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
Clone TypeMonoclonal
Clone No6F187
FormSupplied as a liquid in PBS, pH 7.4, 15mM sodium azide.
PurityPurified by Protein A affinity chromatography
ImmunogenNative SP-A purified from bronchioaveolar lavage from proteinosis patients adsorbed onto aluminum hydroxide gel.
SpecificityRecognizes human pulmonary SP-A. In Western Blot after SDS-PAGE it reacts with reduced forms of SP-A and weaker with non-reduced forms. Reacts specifically with human SP-A in immunohistochemical staining from paraffin embedded tissue samples. Immunoreactivity is seen with alveolar type II cells, nonciliated bronchial cells and a subset of alveolar macrophages. No reactivity in samples from pancreas, intestines, thymus, prostate gland or the peritoneal cavity lining cells. Reacts strongly with SP-A when tested in ELISA with SP-A directly coated onto the microtiter well.
