Application Abreviews Notes
  • Application notes
    ELISA: Use at a concentration of 2 µg/ml.
    IHC-P: 1/20 (human) - 1/400 (rat).
    WB: Use at an assay dependent dilution. Predicted molecular weight: 43 kDa.

    Not tested in other applications.
    Optimal dilutions/concentrations should be determined by the end user.
  • Target

    • Function
      Contributes to the lung's defense against inhaled microorganisms. May participate in the extracellular reorganization or turnover of pulmonary surfactant. Binds strongly maltose residues and to a lesser extent other alpha-glucosyl moieties.
    • Sequence similarities
      Belongs to the SFTPD family.
      Contains 1 C-type lectin domain.
      Contains 1 collagen-like domain.
    • Post-translational
      The N-terminus is blocked.
      Hydroxylation on proline residues within the sequence motif, GXPG, is most likely to be 4-hydroxy as this fits the requirement for 4-hydroxylation in vertebrates.
    • Cellular localization
      Secreted > extracellular space > extracellular matrix. Secreted > extracellular space > surface film.
