  • General notes

    ab234257 is the carrier-free version of ab220423 This format is designed for use in antibody labeling, including fluorochromes, metal isotopes, oligonucleotides, enzymes.

     

    Our carrier-free formats are supplied in a buffer free of BSA, sodium azide and glycerol for higher conjugation efficiency.

    Use our conjugation kits  for antibody conjugates that are ready-to-use in as little as 20 minutes with <1 minute hands-on-time and 100% antibody recovery: available for fluorescent dyes, HRP, biotin and gold.

    Ab234257 is compatible with the Maxpar® Antibody Labeling Kit from Fluidigm.

    Maxpar® is a trademark of Fluidigm Canada Inc.

    Previously labelled as Surfactant protein D.

    Our RabMAb® technology is a patented hybridoma-based technology for making rabbit monoclonal antibodies. For details on our patents, please refer to RabMab® patents.

    This product is a recombinant rabbit monoclonal antibody.

Properties

Applications

Our Abpromise guarantee covers the use of ab234257 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
WB Use at an assay dependent concentration. Detects a band of approximately 43 kDa (predicted molecular weight: 38 kDa).
IHC-P Use at an assay dependent concentration. Perform heat mediated antigen retrieval with Tris/EDTA buffer pH 9.0 before commencing with IHC staining protocol.
IP Use at an assay dependent concentration.

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

    Secreted > extracellular space > extracellular matrix. Secreted > extracellular space > surface film.

  • Negative control: No staining on human skeletal muscle (PMID: 10640760) is observed

    Immunohistochemical analysis of paraffin-embedded human skeletal muscle tissue labeling Surfactant protein D/SP-D with ab220423 at 1/5000 dilution, followed by a ready to use Goat Anti-Rabbit IgG H&L (HRP). Counter stained with Hematoxylin.

    Perform heat mediated antigen retrieval using ab93684 (Tris/EDTA buffer, pH 9.0).

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab220423).

  • Surfactant protein D/SP-D was immunoprecipitated from 0.35 mg human fetal lung lysate with ab220423 at 1/30 dilution. Western blot was performed from the immunoprecipitate using ab220423 at 1/1000 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366), was used for detection at 1/5000 dilution.
    Lane 1: Human fetal lung lysate 10 µg (Input).
    Lane 2: ab220423 IP in human fetal lung lysate.
    Lane 3: Rabbit monoclonal IgG (ab172730) instead of ab220423 in human fetal lung lysate.
    Blocking/Dilution buffer and concentration: 5% NFDM/TBST.
    Exposure time: 3 minutes.

    The molecular mass observed is consistent with what has been described in the literature (PMID: 9751757).

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab220423).

  • Immunohistochemical analysis of paraffin-embedded human lung tissue labeling Surfactant protein D/SP-D with ab220423 at 1/500 dilution, followed by a ready to use Goat Anti-Rabbit IgG H&L (HRP). Cytoplasmic staining on alveolar type II cells of human lung (PMID: 10820266) is observed. Counter stained with Hematoxylin.

    Secondary antibody only control: Used PBS instead of primary antibody, secondary antibody is a ready to use Goat Anti-Rabbit IgG H&L (HRP).

    Perform heat mediated antigen retrieval using ab93684 (Tris/EDTA buffer, pH 9.0).

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab220423).
