- Overview
  - SFTPD Human Recombinant produced in E. Coli is a single, non-glycosylated polypeptide chain containing 175 amino acids (224-375 a.a) and having a molecular mass of 18.9kDa. SFTPD is fused to a 23 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques. Surfactant pulmonary-associated protein D (SFTPD) belongs to the collectin family of C-type lectins, which is synthesized in many tissues including respiratory epithelial cells in the lung, and contains one C-type lectin domain and one collagen-like domain. SFTPD has humoral molecules of the innate immune system, and is deemed a functional candidate in chronic periodontitis. Moreover, SFTPD is involved in the development of acute and chronic inflammation of the lung. A number of human lung diseases are characterized by decreased levels of bronchoalveolar SFTPD. SFTPD contributes to the lungs defense against inhaled microorganisms, organic antigens and toxins. SFTPD interacts with complexes such as bacterial lipopolysaccharides, oligosaccharides and fatty acids and modulates leukocyte action in immune response. In addition, SFTPD participates in the extracellular reorganization or turnover of pulmonary surfactant. SFTPD binds strongly maltose residues and to a lesser extent other alpha-glucosyl moieties.
