Figure 1

Figure 1 demonstrates the blood levels of HB-EGF as detected by ELISA following 5ug/ml trans tympanic delivery and 10ug/kg IV delivery. The negative control represents blood levels measured without any additional HB-EGF exposure. The positive control represents directly injecting 10ug/kg to a blood sample after collection from a non-HB-EGF treated mouse. The number of animal samples used per time point is indicated on each column. HB-EGF (heparin binding epidermal growth factor like growth factor), IV (intravenous), ELISA (enzyme-linked immunosorbent assay)
