Description
Catalogue Number MAB1120
Brand Family Chemicon®
Trade Name
  • Chemicon
Description Anti-Insulin-like Growth Factor-1 Receptor Antibody, α-subunit, clone 24-31
Alternate Names
  • IGF-IR
  • CD221
References
Product Information
Format Purified
Presentation Purified from ascites fluid by Protein G chromatography. Liquid in 10mM PBS, pH 7.4, with 0.2% BSA and 0.09% sodium azide.
Applications
Application Anti-Insulin-like Growth Factor-1 Receptor Antibody, α-subunit, clone 24-31 detects level of Insulin-like Growth Factor-1 Receptor & has been published & validated for use in IH(P) & IP.
Key Applications
  • Immunohistochemistry (Paraffin)
  • Immunoprecipitation
Application Notes 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.
Biological Information
Immunogen IGF-1R/3T3 mouse fibroblasts transfected with human type I IGF-receptor cDNA.
Clone 24-31
Host Mouse
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.
Isotype IgG1
Species Reactivity
  • Human
Antibody Type Monoclonal Antibody
Entrez Gene Number
Entrez Gene Summary This receptor binds insulin-like growth factor with a high affinity. It has tyrosine kinase activity. The insulin-like growth factor I receptor plays a critical role in transformation events. Cleavage of the precursor generates alpha and beta subunits. It is highly overexpressed in most malignant tissues where it functions as an anti-apoptotic agent by enhancing cell survival.
Gene Symbol
  • IGF1R
  • MGC142170
  • MGC18216
  • IGFIR
  • JTK13
  • MGC142172
  • CD221
  • EC 2.7.10.1 [Contains: Insulin-like growth factor 1 receptor alpha chain
  • Insulin-like growth factor 1 receptor beta chain].
UniProt Number
UniProt Summary FUNCTION: SwissProt: P08069 # This receptor binds insulin-like growth factor 1 (IGF1) with a high affinity and IGF2 with a lower affinity. It has a tyrosine-protein kinase activity, which is necessary for the activation of the IGF1-stimulated downstream signaling cascade.
SIZE: 1367 amino acids; 154793 Da
SUBUNIT: Tetramer of 2 alpha and 2 beta chains linked by disulfide bonds. The alpha chains contribute to the formation of the ligand- binding domain, while the beta chain carries the kinase domain. Interacts with PIK3R1 and with the PTB/PID domains of IRS1 and SHC1 in vitro when autophosphorylated on tyrosine residues.
SUBCELLULAR LOCATION: Membrane; Single-pass type I membrane protein.
TISSUE SPECIFICITY: Expressed in a variety of tissues.
PTM: The cytoplasmic domain of the beta subunit is autophosphorylated on tyrosine residues in response to insulin- like growth factor I (IGF I). & Phosphorylation of Tyr-980 is required for IRS1- and SHC1- binding.
DISEASE: SwissProt: P08069 # Defects in IGF1R may be a cause in some cases of resistance to insulin-like growth factor 1 (IGF1 resistance) [MIM:270450]. IGF1 resistance is a gowth deficiency disorder characterized by intrauterine growth retardation and poor postnatal growth accompanied with increased plasma IGF1.
SIMILARITY: SwissProt: P08069 ## Belongs to the protein kinase superfamily. Tyr protein kinase family. Insulin receptor subfamily. & Contains 3 fibronectin type-III domains. & Contains 1 protein kinase domain.
