Application Abreviews Notes
WB 1/1000. Detects a band of approximately 43 kDa (predicted molecular weight: 38 kDa).
IHC-P 1/5000. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.

The Mouse species recommendation is based on the WB results. We do not guarantee IHC-P for Mouse.
IHC-Fr 1/500.

Perform heat-mediated antigen retrieval by using Tris-EDTA buffer (pH 9.0).

The Mouse species recommendation is based on the WB results. We do not guarantee IHC-F for Mouse.

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
    modifications

    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
