Gene Information

human ... IGF1R(3480)

Specificity

Recognizes the alpha-subunit of type I Insulin-like Growth Factor Receptor (IGF-1R). It shows no cross-reaction with insulin receptor. Its epitope localizes between a.a. 283-440 (exon 4-6) of IGF-1R. Both IGF-1R and insulin receptor are synthesized as a single polypeptide which is glycosylated and proteolytically cleaved to give the alpha- and beta-subunits, which are disulfide-linked in a beta-alpha-alpha-beta configuration in the mature receptor. The a-subunit is completely extracellular, while the beta-subunit spans the membrane and the intracellular portion has intrinsic tyrosine kinase activity. It is assumed that, as for the insulin receptor, the tyrosine kinase activity is essential for IGF-1 action.

Weakly reacts with Rabbit.

Immunogen

IGF-1R/3T3 mouse fibroblasts transfected with human type I IGF-receptor cDNA.

Application

Acts as a Weak IGF-like Agonist in Bioassays (Thymidine incorporation into DNA)

Immunoprecipitation (Use Protein G): 2μg antibody/mg protein lysate.

Immunohistochemistry (Frozen and formalin/paraffin): Use antibody at 2-4ug/mL for 30 min. at room temperature. Staining of formalin-fixed tissues requires boiling tissue sections in 1 mM EDTA, pH 8.0, for 10-20 min. followed by cooling at room temperature for 20 minutes. Please note that EDTA is better than citrate for epitope unmasking.

Optimal working dilutions must be determined by end user.

Insulin-like growth factor-I (IGF-I) is an essential growth factor that regulates the processes necessary for cell proliferation, differentiation, and survival. The Igf1 gene encodes mature IGF-I and a carboxy-terminal extension called the E-peptide. In rodents, alternative splicing and post-translational processing
