    Highly pure (>98%) recombinant hIGF-1 (human Insulin Like Growth Factor-1).



Our Abpromise guarantee covers the use of ab9572 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
IHC-P Use a concentration of 4 µg/ml. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
WB Use at an assay dependent concentration. To detect hIGF-1 by Western Blot analysis this antibody can be used at a concentration of 0.1 - 0.2 µg/ml. Used in conjunction with compatible secondary reagents the detection limit for recombinant hIGF-1 is 1.5 - 3.0 ng/lane, under either reducing or non-reducing conditions.
Neutralising Use at an assay dependent concentration. To yield one-half maximal inhibition of the biological activity of hIGF-1 (5.0 ng/ml), a concentration of 0.67 - 1.0 ug/ml of this antibody is required.
IHC-FoFr Use at an assay dependent concentration. PubMed: 28754163
ICC/IF 1/200.
Sandwich ELISA Use a concentration of 0.5 - 2 µg/ml. Can be paired for Sandwich ELISA with Rabbit polyclonal to IGF1 (Biotin) (ab83137). Allows for the detection of at least 0.2 - 0.4 ng/well of recombinant IGF1.


  • Function
    The insulin-like growth factors, isolated from plasma, are structurally and functionally related to insulin but have a much higher growth-promoting activity. May be a physiological regulator of [1-14C]-2-deoxy-D-glucose (2DG) transport and glycogen synthesis in osteoblasts. Stimulates glucose transport in rat bone-derived osteoblastic (PyMS) cells and is effective at much lower concentrations than insulin, not only regarding glycogen and DNA synthesis but also with regard to enhancing glucose uptake.
  • Involvement in disease
    Defects in IGF1 are the cause of insulin-like growth factor I deficiency (IGF1 deficiency) [MIM:608747]. IGF1 deficiency is an autosomal recessive disorder characterized by growth retardation, sensorineural deafness and mental retardation.
  • Sequence similarities
    Belongs to the insulin family.
  • Cellular localization
  • Information by UniProt
  • Database links
  • Form
    There are 2 isoforms produced by alternative splicing. Isoform 1 also known as: IGF-IB; Isoform 2 also known as: IGF-IA.

  • Ab9572 staining Human normal liver parenchyma. Staining is localised to the cytoplasm.
    Left panel: with primary antibody at 4 ug/ml. Right panel: isotype control.
    Sections were stained using an automated system DAKO Autostainer Plus , at room temperature: sections were rehydrated and antigen retrieved with the Dako 3 in 1 AR buffer EDTA pH 9.0 in a DAKO PT Link. Slides were peroxidase blocked in 3% H2O2 in methanol for 10 mins. They were then blocked with Dako Protein block for 10 minutes (containing casein 0.25% in PBS) then incubated with primary antibody for 20 min and detected with Dako envision flex amplification kit for 30 minutes. Colorimetric detection was completed with Diaminobenzidine for 5 minutes. Slides were counterstained with Haematoxylin and coverslipped under DePeX. Please note that for manual staining we recommend to optimize the primary antibody concentration and incubation time (overnight incubation), and amplification may be required.
  • ab9572 staining IGF1 in mouse heart tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with 10% formalin and blocked with 10% serum for 30 minutes at 25°C; antigen retrieval was by heat mediation. Samples were incubated with primary antibody (1/1000 in 10% goat serum) for 24 hours at 4°C. An Alexa Fluor® 594-conjugated goat anti-rabbit IgG polyclonal (1/400) was used as the secondary antibody.

  • ICC/IF image of ab9572 stained human embryonic stem cells. The cells were fixed in methanol and then incubated in 10% BSA for 1 hour to block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab9572, 1/200) overnight at +4°C. The secondary antibody (red) was an Alexa Fluor® 568 goat anti-rabbit used at a 1/400 dilution.
