Human Phospho-HGFR/c-MET DuoSet IC ELISA Summary

Assay Type
Solid Phase Sandwich ELISA
96-well strip plate
Sample Volume Required
Cell lysates (100 µL)
Sufficient Materials
Kits available for two, five, or fifteen 96-well plates*
Please see the product datasheet

* Provided that the recommended microplates, buffers, diluents, substrates and solutions are used, and the assay is run as summarized in the Assay Procedure provided.

This DuoSet IC ELISA contains the basic components required for the development of sandwich ELISAs to measure tyrosine-phosphorylated human HGF R / c-MET in cell lysates. An immobilized capture antibody specific for HGF R / c-MET binds both phosphorylated and unphosphorylated HGF R / c-MET. After washing away unbound material, a biotinylated detection antibody is used to detect only phosphorylated receptor, utilizing a standard HRP format.

Scientific Data

Figure 1. The Human Phospho-HGF R DuoSet IC ELISA is more sensitive than immunoprecipitation (IP)-Western analysis The human epidermoid carcinoma cell line, A431, was treated with 100 ng/mL recombinant human HGF for five minutes to induce tyrosine phosphorylation of HGF R. Serial dilutions of lysates were analyzed by (A) IP-Western blot and (B) this ELISA. IPs were done using an anti-HGF R polyclonal antibody and Protein G agarose. Immunoblots were incubated with a biotinylated anti-phosphotyrosine monoclonal antibody (Catalog # BAM1676) to detect phospho-HGF R (p-HGF R). Bands were visualized with Streptavidin-HRP (Cat # DY998) followed by chemiluminescent detection using WesternGloTM Chemiluminescent Detection Substrate (Catalog # AR004).

Figure 2. The Human Phospho-HGF RDuoSet IC ELISA detects ligand-induced HGF R tyrosine phosphorylation A431 cells were untreated or treated with 100 ng/mL recombinant human HGF for five minutes. ELISA and IP-Western blot (inset) analyses were done using 50 μg and 500 μg of lysate, respectively. IP-Western blots for phospho-HGF R (p-HGF R) were done as described in Figure 1. Blots were stripped and total HGF R was detected using a biotinylated anti-HGF R polyclonal antibody (Catalog # BAF358).

Figure 3. The specificity of the Human Phospho-HGF RDuoSet IC ELISA is confirmed by receptor competition A431 cells were treated with 100 ng/mL recombinant human HGF for five minutes. The indicated amounts of recombinant extracellular domains of human HGF R (Catalog #358-MT), human EGF R (Catalog #1095-ER) or human IGF-I sR (Catalog #305-GR) were added to 50 μg lysate and analyzed using this ELISA. Competition was observed only with recombinant HGF R.

Background: HGFR/c-MET

HGF receptor, a product of the proto-oncogene c-met, is a heterodimeric transmembrane glycoprotein that is a receptor-type tyrosine kinase. c-MET is synthesized as a single-chain precursor (pr170) which undergoes post-translational glycosylation and proteolytic cleavage to give rise to the heterodimeric mature form.

Long Name:
