The Human HB-EGF (Heparin-binding EGF-like Growth Factor) ELISA (Enzyme-Linked Immunosorbent Assay) kit is an in vitro enzyme-linked immunosorbent assay for the quantitative measurement of human HB-EGF in serum (human HB-EGF concentration is pretty low in normal serum/plasma, it may not be detected in this assay), plasma, cell culture supernatants and urine.
