FunctionThe 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 diseaseDefects 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 similaritiesBelongs to the insulin family.

Anti-IGF1 antibody [EPR5098(2)] (ab133542) at 1/1000 dilution + Recombinant human IGF-I fragment at 0.005 µg
Predicted band size: 22 kDa
This data was developed using ab133542, the same antibody clone in a different buffer formulation.
The recombinant IGF-I fragment corresponds to amino acids 49-118 of human IGF-1 with the molecular weight of 10kDa.
This data was developed using ab133542, the same antibody clone in a different buffer formulation.Primary antibody, ab33542 was used at concentrations between 0.1 - 1000ng/ml. An Alkaline Phosphatase AffiniPure Goat Anti-Rabbit IgG (H+L) was used as the secondary antibody at 1:2500 dilution. Antigen concentration was 1000ng/ml.
