Human IGFBP-1 antiserum was prepared by immunising rabbits with a 12 amino acid peptide derived from the central domain of human IGFBP-1 linked to diphtheria toxoid. The peptide sequence is located immediately upstream of the thyroglobulin type-1 domain and is unique to IGFBP-1. As a consequence, the antiserum recognises human IGFBP-1 but not IGFBP-2, 3, 4, 5 or 6 or related proteins. Although the sequence is specific to human IGFBP-1, the antiserum does recognise rat and mouse IGFBP-1. Sequence analysis suggests that it should be specific for IGFBP-1 in non-human primates and may also work in a number of other species, although this should be experimentally determined.
