Biotinylated IGF´s and analogs have found a wide range of applications in in-vitro and in-vivo and are a safe and stable alternative to 125 I-lableld IGF´s. As 125 I-lableld IGFBP´s have also been used for methods as e.g. proteolysis assays, binding studies and in-vivo studies, there should be some potential for biotinylated IGFBP´s, too. A literature search on the use of biotinylated IGFBP´s resulted in a small number of reports, which are limited to IGFBP-1(1-3), IGFBP-2 (4,5), IGFBP-3 (6-14, 16) and IGFBP-4 (15). Until today we found no scientific papers on the use of biotinylated IGFBP-5 and IGFBP-6.
Though there is small number of papers, the authors have used the biotinylated IGFBP´s in a broad range of techniques to study IGF-dependent and IGF-independent actions of IGFBP´s. Biotinylated IGFBP´s have been used in immunoassays (1, 6, 11, 15), proteolysis studies (2,3), ligand blot (4,10, 12, 16), cross-linking studies (9, 12) and binding studies (1, 4, 5, 7, 8, 13). Biotinylated IGFBP-3 has been used to demonstrate the nuclear appearance of IGFBP-3 invivo (14).
