    See all Surfactant protein D/SP-D primary antibodies
  • Description

    Mouse monoclonal [10B2] to Surfactant protein D/SP-D
  • Host species

  • Specificity

    This antibody is specific for Surfactant protein D/SP-D from amniotic fluid, serum and bronchioalveolar lavage. In Western Blotting this antibody reacts with non-reduced Surfactant protein D/SP-D only.

  • Tested applications

    Suitable for: ELISA, WBmore details
  • Species reactivity

    Reacts with: Human
  • Immunogen

    Full length native protein (purified) corresponding to Human Surfactant protein D/SP-D. (Surfactant protein D/ SP-D purified from late pregnancy amniotic fluid.)

  • Epitope

    The epitope this antibody reacts with is localised within the c-terminal neck (CRD) of Surfactant protein D/SP-D.
  • General notes


    This antibody does not influence Surfactant protein D's / SP-D's binding to carbohydrates.

    Previously labelled as Surfactant protein D.



Our Abpromise guarantee covers the use of ab26267 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
ELISA 1/2000.
WB 1/2000. Predicted molecular weight: 38 kDa.


  • 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.
