Reproducibility is key to advancing scientific discovery and accelerating scientists’ next breakthrough.
Abcam is leading the way with our range of recombinant antibodies, knockout-validated antibodies and knockout cell lines, all of which support improved reproducibility.
We are also planning to innovate the way in which we present recommended applications and species on our product datasheets, so that only applications & species that have been tested in our own labs, our suppliers or by selected trusted collaborators are covered by our Abpromise™ guarantee.
In preparation for this, we have started to update the applications & species that this product is Abpromise guaranteed for.
We are also updating the applications & species that this product has been “predicted to work with,” however this information is not covered by our Abpromise guarantee.
Applications & species from publications and Abreviews that have not been tested in our own labs or in those of our suppliers are not covered by the Abpromise guarantee.

Our Abpromise guarantee covers the use of ab193910 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|WB||1/1000. Detects a band of approximately 32 kDa (predicted molecular weight: 32 kDa).|
FunctionIGF-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 specificityExpressed by most tissues. Present in plasma.
Sequence similaritiesContains 1 IGFBP N-terminal domain.
Contains 1 thyroglobulin type-1 domain.
Developmental stageIGFBP3 levels are higher during extrauterine life and peak during puberty.
DomainThe thyroglobulin type-1 domain mediates interaction with HN.
modificationsPhosphorylation sites are present in the extracelllular medium.

Anti-IGFBP3 antibody [EPR18680-153] (ab193910) at 1/1000 dilution + Human serum at 10 µg
VeriBlot for IP Detection Reagent (HRP) (ab131366) at 1/2000 dilution (VeriBlot for IP Detection Reagent (HRP))
Developed using the ECL technique.
Predicted band size: 32 kDa
Observed band size: 32 kDa
Exposure time: 10 seconds
Blocking and dilution buffer: 5% NFDM/TBST.
IGFBP3 was immunoprecipitated from 0.35 mg of human serum with ab193910 at 1/70 dilution. Western blot was performed from the immunoprecipitate using ab193910 at 1/500 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366), was used for detection at 1/1000 dilution.
Lane 1: Human serum 10 μg (Input).
Lane 2: ab193910 IP in human serum.
Lane 3: Rabbit monoclonal IgG (ab172730) instead of ab193910 in human serum.
Blocking and dilution buffer and concentration: 5% NFDM/TBST.
Exposure time: 3 seconds.
The bands at 41 kDa and 44 kDa have previously been documented as IGFBP3 doublets (PMID:16816363).
