Our Abpromise guarantee covers the use of ab109790 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
Indirect ELISA Use a concentration of 0.5 - 2 µg/ml. (using 100 µl/well antibody solution) allows the detection of at least 0.2 - 0.4 ng/well of recombinant Human IGFBP3.
Sandwich ELISA Use a concentration of 0.5 - 2 µg/ml. Can be paired for Sandwich ELISA with Rabbit polyclonal to IGFBP3 (Biotin) (ab84228). Using ab84228 as the detection antibody and ab109790 as the capture antibody, the detection limit for recombinant Human IGFBP3 is 0.2 - 0.4 ng/well, using 100 µl/well antibody solution.
WB Use a concentration of 0.1 - 0.2 µg/ml. Predicted molecular weight: 32 kDa. The detection limit for recombinant Human IGFBP3 is 1.5 - 3.0 ng/lane, under either reducing or non-reducing conditions


  • Function
    IGF-binding proteins prolong the half-life of the IGFs and have been shown to either inhibit or stimulate the growth promoting effects of the IGFs on cell culture. They alter the interaction of IGFs with their cell surface receptors.
  • Tissue specificity
    Expressed by most tissues. Present in plasma.
  • Sequence similarities
    Contains 1 IGFBP N-terminal domain.
    Contains 1 thyroglobulin type-1 domain.
  • Developmental stage
    IGFBP3 levels are higher during extrauterine life and peak during puberty.
  • Domain
    The thyroglobulin type-1 domain mediates interaction with HN.
  • Post-translational
    Phosphorylation sites are present in the extracelllular medium.

Thank you for your reply.

I can confirm that ab84228 can be paired for Sandwich ELISA with Rabbit polyclonal to IGFBP3 (ab109790). I can suggest touse the polyclonal ab84228 as the detection antibody as this is the conjugated one (biotin con...
