This tag-free recombinant human EGF fragment (residues 971–1023) demonstrates potent mitogenic activity with an ED50 of 60–450 pg/mL in BALB/c 3T3 cell proliferation assays, confirming robust EGFR-binding competence suitable for dose-response and receptor-ligand competition studies via ELISA or SPR. The 53-amino-acid sequence corresponds to the mature, processed EGF domain, and its E. coli expression yields a non-glycosylated form that provides a defined, homogeneous ligand—eliminating glycan-related variability that can confound quantitative binding kinetics. This protein supports use in wound healing scratch assays, stem cell maintenance or differentiation protocols, and as a calibration standard for antibody characterization experiments. Purity exceeding 95% by SDS-PAGE combined with endotoxin levels below 1.0 EU/μg satisfies the criteria typical for cell-based bioassays and in vivo tumor biology models where endotoxin interference must be minimized.
