Validation Data Gallery

• 

  Purity of recombinant human EGF was determined by SDS- polyacrylamide gel electrophoresis. The protein was resolved in an SDS- polyacrylamide gel in reducing and non-reducing conditions and stained using Coomassie blue.

• 

  Recombinant human EGF (HZ-1326) induces dose-dependent proliferation of the 4MBr-5 (monkey epithelial) cell line. Cell number was quantitatively assessed by PrestoBlue® cell viability reagent. 4MBr-5 cells were treated with increasing concentrations of recombinant EGF for 120 hours. The EC50 was determined using a 4-parameter non-linear regression model. The EC50 range is 0.1-0.6 ng/mL.

Background

EGF (epidermal growth factor) is a 6 kDA, single chain protein that serves a mitogenic factor for numerous cell types, particularly epithelial cells and fibroblasts. It is predominantly produced and secreted by the kidneys in humans. EGF activates cells through binding with its corresponding receptor (EGFR). Receptor binding activates several downstream pathways leading to cell proliferation, differentiation, and apoptosis. EGF plays important roles in embryonic development, tissue regeneration, transport through ion channels, and wound healing. Dysregulated EGF signaling has been linked with renal disease progression, and EGF levels could potentially be used as biomarker to monitor disease-related cell damage (PMID: 15110798, 24513230, 27868030).
