Human Epidermal Growth Factor (GenBank Accession No. NM_001963), a.a. 971- 1023, MW=6.2 kDa, expressed in an E. coli expression system.

P01133

epidermal growth factor, EGF, beta-urogastrone

≥98% by SDS-PAGE and HPLC analysis.

< 1EU per µg of EGF as determined by the LAL method.

ED50 is < 0.1 ng/ml. ED50 was determined by a cell proliferation assay using BALB/c 3T3 cells

Lyophilized  from  a  sterile  filtered  solution  containing  10  mM  Phosphate Buffered Saline (PBS), pH 7.4, 138 mM NaCl, and 2.7 mM KCl.

lyophilized protein

Reconstitute at 0.1-1.0 mg/ml in distilled water. This solution can then be diluted into other buffers. To maximize product collection from vial surface, vortex briefly and then spin down to recollect the liquid.

≥2 years (lyophilized) at -20°C.

Useful for cell culture and for the study of signaling pathways. Also useful for receptor binding studies, screening inhibitors, and selectivity profiling.
