Human IGF-1 R (Luc) HEK293 Reporter Cell

For research use only.

描述(Description)

The Human IGF-1 R (Luc) HEK293 Reporter Cell was engineered to not only express signaling response element, but also express the receptor full length human IGF-1 R (Gene ID: 3480). When stimulated with human IGF-1 protein, the IGF-1/IGF-1 R interaction drives RE-mediated luminescence. Neutralization of biological effect of human IGF-1 protein by corresponding antibody results in a decrease in luminescence.

应用说明(Application)

• Screen for neutralizing antibodies blocking the stimulation of human IGF-1 protein.

Receptor Assay

IGF-I R FACS

Expression analysis of human IGF-1 R on Human IGF-1 R (Luc) HEK293 Reporter Cell by FACS.
Cell surface staining was performed on Human IGF-1 R (Luc) HEK293 Reporter Cell or negative control cell using PE-labeled anti-human IGF-1 R antibody.

Protocol

 

Application

IGF-I R APPLICATION

Inhibition of human IGF-1 protein-induced reporter activity.
This reporter cell was incubated with serial dilutions of antibodies in the presence of human IGF-1 protein (Cat. No. IG1-H5245) with a final concentration of 0.1 μg/mL. The EC50 of anti-human IGF-1 R neutralizing antibody (Teprotumumab) is approximately 0.12 μg/mL.

Protocol

 

Signaling Bioassay

IGF-I R SIGNALING

Response to human IGF-1 protein (RLU).
This reporter cell was incubated with serial dilutions of human IGF-1 protein (Cat. No. IG1-H5245). The EC50 was approximately 0.10 μg/mL.

Protocol

IGF-I R SIGNALING

Response to human IGF-1 protein (FOLD).
This reporter cell was incubated with serial dilutions of human IGF-1 protein (Cat. No. IG1-H5245). The max induction fold was approximately 16.37.

Protocol

 

Passage Stability

IGF-I R PASSAGE

Passage stability analysis by Signaling Bioassay.
The continuously growing Human IGF-1 R (Luc) HEK293 Reporter Cell was stimulated with serial dilutions of human IGF-1 protein (Cat. No. IG1-H5245). Human IGF-1 protein stimulated response demonstrates passage stabilization (fold induction and EC50) across passage 15-24.

背景(Background)

The Insulin-like Growth Factor 1 Receptor (IGF1) is also known as CD221, JTK13. and is a transmembrane receptor that is activated by IGF-1 and by the related growth factor IGF-2. It belongs to the large class of tyrosine kinase receptors. This receptor mediates the effects of IGF-1, which is a polypeptide protein hormone similar in molecular structure to insulin. IGF1R is make up of two alpha subunits and two beta subunits ,the Both the α and β subunits are synthesized from a single mRNA precursor. The precursor is then glycosylated, proteolytically cleaved, and crosslinked by cysteine bonds to form a functional transmembrane αβ chain.The α chains are located extracellularly while the β subunit spans the membrane and are responsible for intracellular signal transduction upon ligand stimulation. IGF1R have a binding site for ATP, which is used to provide the phosphates for autophosphorylation. There is a 60% homology between IGF1R and the insulin receptor. In response to ligand binding, the α chains induce the tyrosine autophosphorylation of the β chains. This event triggers a cascade of intracellular signaling that, while somewhat cell type specific, often promotes cell survival and cell proliferation.
