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
Applications	Suitable for use in ELISA, Western Blot and Immunohistochemistry. Other applications not tested.
Recommended Dilutions	Optimal dilutions to be determined by the researcher.
Hybridoma	X63-Ag8.653. Female CF1 x Balb/c mice immunized i.p. with immunogen adsorbed onto Al(OH)3.
Culture Medium	RPMI 1640 with 10% fetal calf serum
Storage and Stability	May 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. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
CAS Number	n/a
Clone Type	Monoclonal
Isotype	IgG1,k
Clone No	6F187
Host	Mouse
Source	Human
Concentration	~1mg/ml
Form	Supplied as a liquid in PBS, pH 7.4, 15mM sodium azide.
Purity	Purified by Protein A/G affinity chromatography
Immunogen	Native SP-A purified from bronchioaveolar lavage from proteinosis patients adsorbed onto aluminum hydroxide gel.
Specificity	Recognizes 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.
