Description: This 1H7 monoclonal antibody reacts with human insulin-like growth factor-1 receptor (IGF-1R), also known as CD221. This receptor is a cell surface-expressed glycoprotein composed of two extracellular alpha subunits and two transmembrane beta subunits that possess tyrosine kinase activity. Expressed on nearly all cell types, this receptor binds IGF-I and IGF-II, as well as insulin. Ligand binding leads to activation of the PI3K/Akt and MAPK pathways, which mediate cell proliferation and survival. Many tumors and transformed cells display altered IGF-1R expression. This monoclonal antibody has been reported to block binding of IGF-I and IGF-II to the IGF-1R. Applications Reported: This 1H7 antibody has been reported for use in flow cytometric analysis. Applications Tested: This 1H7 antibody has been pre-titrated and tested by flow cytometric analysis of the HeLa cell line. This can be used at 5 µL (0.25 µg) per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. Excitation: 633-647 nm; Emission: 660 nm; Laser: Red Laser. Filtration: 0.2 µm post-manufacturing filtered.

Insulin growth factor 1 receptor belongs to the family of tyrosine receptor kinases. It is involved in activation of various substrates including IGF and neurotensin, regulation of metabolism, cell division, maintece, and inflammation response. The protein is a tetramer consisting of two alpha, and two beta subunits. The alpha-subunits binds to insulin growth factor 1 with higher affinity than to insulin growth factor 2. Binding results in a conformational change, followed by autophosphorylation of IGF-1R at positions 1134, 1135, 1136. The activated IGF-1R in turn, causes phosphorylation of substrate proteins, followed by sequential activation of RAS, RAF, and mitogen-activated protein kinase isoforms ERK, p38, and JNK, leading to the transcription of genes that drive proliferation. This antibody recognizes the beta-subunit of IGF-1R.
