General description

Surfactant Protein D (SFTPD) belongs to the collectin family of multimeric glycoproteins and exists as oligomeric structure or a trimeric subunit. The human SFTPD corresponds to a molecular weight of 150kDa and the trimer is close to 620 kDa. Anti-Surfactant Protein D antibody, Mouse monoclonal, (mouse IgG1 isotype) is derived from the 10F6E12 hybridoma, produced by the fusion of mouse myeloma cells and splenocytes from mouse immunized with mouse recombinant SP-D.

Surfactant Protein D (SP-D) contains an N-terminal cysteine-rich domain, a collagenous domain, a neck region and a C-terminal carbohydrate recognition domain (CRD). The gene is located on human chromosome 14. SP-D is expressed in lungs and kidney.


Mouse recombinant SP-D


Anti-Surfactant Protein D antibody, Mouse monoclonal may be used in immunoblotting.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide

Biochem/physiol Actions

Surfactant Protein D (SFTPD) imparts pulmonary defense during fungal infection. It favors pulmonary inflammation. It recognizes the surface lipopolysaccharide (LPS) of pathogens and acts as first-line host defense molecule. It also recognizes the viral glycoprotein hemagglutinin (HA) present in viral surface. Polymorphism in the SFTPD gene may lead to decreased levels of the protein and high risk for chronic obstructive pulmonary disease (COPD).

Surfactant Protein D (SP-D) plays a critical role in the innate host defense and the modulation of inflammatory responses in infectious diseases. It aids the uptake and clearance of pathogens and apoptotic cells. SP-D maintains surfactant homeostasis. It reduces the surface tension at the air-liquid interface and blocks the lung from collapsing.
