This antibody is specific to IGF1 (Insulin like Growth Factor 1) and shows minimal cross-reaction with IGF11, Proinsulin, MSF, and Insulin. IGF1 is a polypeptide growth factor with two isoforms that are produced by alternative splicing. Isoform 1 is also known as IGF1B while isoform 2 is known as IGF1A. IGF1 stimulates the proliferation of a wide range of cell types including muscle, bone and cartilage tissue. It functions as an autocrine regulator of growth. Activation of the IGF system has emerged as a key factor for tumor progression and resistance to apoptosis in many cancers like those of breast, thyroid and colon.

Store the IGF1 antibody at 2-8°C (with azide) or aliquot and store at -20°C or colder (without azide).
