Elevated HGF levels in sera from breast cancer patients detected using a protein microarray ELISA

J Proteome Res. May-Jun 2002;1(3):233-7. doi: 10.1021/pr025506q.

Abstract

We developed an ELISA in high-density microarray format to detect hepatocyte growth factor (HGF) in human serum. The microassay can detect HGF at sub-pg/mL concentrations in sample volumes of 100 microL or less. The microassay is also quantitative and was used to detect elevated HGF levels in sera from recurrent breast cancer patients. The microarray format provides the potential for high-throughput quantitation of multiple biomarkers in parallel, as demonstrated with a multiplex analysis of five biomarker proteins.
