Product Summary

The Quantikine Human HB-EGF Immunoassay is a 4.5 hour solid-phase ELISA designed to measure human HB-EGF in cell culture supernates, serum, plasma, saliva, urine, and human milk. It contains Sf 21-expressed recombinant human HB-EGF and antibodies raised against the recombinant factor. Results obtained using natural human HB-EGF showed linear curves that were parallel to the standard curves obtained using the Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for naturally occurring
human HB-EGF.

Precision

Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested twenty times on one plate to assess intra-assay precision
Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in twenty separate assays to assess inter-assay precision. Assays were performed by at least three technicians using two lots of components

Recovery

The recovery of human HB-EGF spiked to levels throughout the range of the assay in various matrices was evaluated.

Sample Type Average % Recovery Range %
Cell Culture Media (n=4) 120 113-125
EDTA Plasma (n=4) 99 83-114
Heparin Plasma (n=4) 84 75-96
Platelet-poor EDTA Plasma (n=4) 101 84-119

Serum (n=4) 95 79-107
Urine (n=4) 98 81-121

Linearity

To assess the linearity of the assay, samples containing and/or spiked with high concentrations of human HB-EGF were diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay.

Background: HB-EGF

HB-EGF (Heparin-Binding EGF-like growth factor), also known as DTR, is produced by bronchial epithelium, visceral and vascular smooth muscle, CD4+ T cells, cardiac muscle, glomerular podocytes, keratinocytes, and IL-10-secreting regulatory macrophages. It activates both the EGF R/ErbB1 and ErbB4 receptors and has been linked to many cellular processes including proliferation, apoptosis, cell migration/invasion, differentiation, morphogenesis, and development. HB-EGF is also involved in several aspects of cancer development and progression.

Long Name:
Heparin Binding EGF-like Growth Factor
Entrez Gene IDs:
