Recombinant Antibody
Specificity
This antibody is specific for the human insulin-like growth factor 1 receptor (IGF1R). It recognises the extracellular portion of the receptor, specifically an epitope in the alpha subunit (amino acids 440-514). It does not cross-react with rat or mouse IGF1R or human insulin receptors in co-precipitation or immunodepletion assays.
Alternative Names
CD221; IGF1 receptor; Insulin-like growth factor 1 receptor; type I IGF receptor; Insulin-like growth factor I receptor; IGF-I receptor; 24 55
UniProt
P08069
Immunogen
This antibody was raised by immunising BALB/c mice with transfected mouse fibroblasts expressing high levels of human IGF1R (IGF1R/3T3).
Application Notes
The ability of this antibody to bind human IGF1R has been confirmed in IGF1 binding assays using both IG1FR-overexpressing IGF1R/3T3 cells and soluble receptors (Soos et al, 1992). This antibody efficiently precipitates IGF1R from lysates of IGF1R-transfected cells (Kavran et al, 2014; Soos et al, 1992), as well as receptor-IGF1 complexes (Soos et al, 1992). When immobilised, this antibody has been shown to remove essentially all soluble IGF1R in immunodepletion experiments (Soos et al, 1992).This antibody weakly inhibits IGF1 binding to its receptor (Soos et al, 1993).
