Heparin-binding epidermal growth factor-like growth factor (HB-EGF) is synthesized as a membrane-bound precursor and cleaved by protease to produce a soluble mature growth factor, HB-EGF ( References 1 and 2). The former works as a juxtacrine growth factor and the latter works as a paracrine growth factor. Soluble HB-EGF has various molecular weights of 19-27 kDa in Western blotting due to heterogeneous O-glycosylation and N-terminal truncation.

HB-EGF activates EGFR and ErbB4 and promotes differentiation in many tissues. In humans, Pro HB-EGF is a cell surface receptor for diphtheria toxin (Reference 3). CRM197, a non-toxic mutant of diphtheria toxin, inhibits the function of HB-EGF. Since HB-EGF is highly expressed in most ovarian cancers, CRM197 has been tried as an anticancer agent (Reference 4). Hybridoma clone 4G10 was created in the laboratory of Prof. Mekada, Osaka University (References 3 and 4).
Figure Identification of human HB-EGF by using anti-HB-EGF (clone 4G10)

(a) Western blotting
Sample 1: Vero cell extract
Sample 2: Vero cells carrrying human HB-EGF expression vector
Sample 3: Vero cells carrying mouse HB-EGF expression vector

(b) Immunoprecipitation
Samples are the same as (a) except that the cell surface was biotinylated.

(c) Immuno-cytochemistry
Samples; (Vero-H) Vero cells carrying human HG-EGF expression vector, (Vero-mH) Vero cells carrying mouse HB-EGF expression vector. Cells treated with antibody 4G10 were fixed with 4% PFA and reacted with Cys3 conjugated 2nd antibody
