    Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/20000 dilution

    Developed using the ECL technique.

    Predicted band size: 38 kDa
    Observed band size: 43 kDa
    why is the actual band size different from the predicted?


    Exposure time: 3 minutes


    Blocking/Dilution buffer: 5% NFDM/TBST.

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

    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).

    Immunoprecipitation - Anti-Surfactant protein D/SP-D antibody [EPR21928-209] (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).
