Our Abpromise guarantee covers the use of ab15688 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
  • 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.

    Thank you for this additional information. A few suggestions just to follow a protocol a little more similar to how we have tested. We generally recommend blocking in 5% milk in TBST and incubating the primary antibody overnight at 4 degrees. You may also wish to try changing your lysis buffer to RIPA if possible.

    At Abcam, providing quality service is just as important as providing quality products. Our Abpromise® ensures that you can trust our products to perform as stated on the datasheets, or we will offer a replacement, credit, or refund within 6 months of purchase.

    The Abcam Abpromise® guarantee:
    - 100% Scientific and Customer Support for any product you buy from Abcam or one of our authorized distributors.
    - We guarantee our products work in the tested species and applications stated on the datasheet.
    - We will replace or refund products not performing as stated on the datasheet if reported within 6 months of purchase.
    - We investigate any quality concerns raised by customers to ensure our catalog contains products that perform to the highest standards.

    Please note these conditions to our Abpromise®:
    - Protocol information must be provided in order for the claim to be validated.
    - Antibodies tested in recombinant samples only are not guaranteed for use on endogenous samples.
    - “Predicted to react” information on the datasheets is provided for reference only and these species are not guaranteed.
    - Fast Track antibodies are covered for ELISA against the immunizing peptide only.

    I hope this information is helpful, but please do not hesitate to contact us with further questions.
