General description

Insulin-like growth factors -1 and -2 are important regulators of signalling that mediates growth and metabolism in cells. Insulin-like growth factor -1 shares structural homology with proinsulin and is mainly produced by liver. IGF-1 acts via specific receptor, IGF-1R, a heterodimeric tyrosine kinase receptor that signals to various second messenger pathways such as MAPK, Raf/Ras and PI3K cascades. The effect of IGF-1 is by endocrine, paracrine and autocrine signalling. The effects of IGF-1 signalling are important at many developmental levels from cells to organ to organism, growth, differentiation, anti-apoptosis, proliferation and transformation. Irregular IGF-1 signaling has been implicated in many cancers including melanoma, breast, lung, colon and prostate
Anti-IGF-I recognizes human insulin-like growth factor I. The antibody does not react with human IGF-II.

Specificity

The antibody neutralizes the biological activity of recombinant human IGF-I.

Immunogen

recombinant human IGF-I expressed in Escherichia coli

Application

Anti- IGF-1 antibody may be used for neutralization reactions, the ND50 of the antibody is 3-12 μg/ml. For immunoblotting a working antibody concentration of 0.1-0.2 μg/ml.

Physical form

Lyophilized from a 0.2 μm filtered solution of phosphate buffered saline, pH 7.4, with 5% trehalose.

Preparation Note

Affinity isolated by IGF-I affinity chromatography.
