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.
|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.|
|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.|
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.
