Endotoxin: Less than 0.1ng/μg (1 EU/μg) of recombinant human Epidermal Growth Factor (EGF) as determined by LAL test.
Reconstitution: It is recommended to reconstitute the lyophilized recombinant human Epidermal Growth Factor (EGF) in sterile 18 MΩ-cm H2O not less than 100 µg/ml, which can then be further diluted to other aqueous solutions.
Storage: Lyophilized recombinant Human Epidermal Growth Factor (rhEGF) remains stable up to 12 months at -80°C from date of receipt. Upon reconstitution, rhEGF should be stable up to 4 weeks at 4°C or up to 6 months at -20°C.
Usage: This material is offered by USA Bioworld biotech for research, laboratory or further evaluation purposes. For research use only.
Description: Epidermal Growth Factor (EGF) is a polypeptide growth factor which stimulates the proliferation of a wide range of epidermal and epithelial cells. Recombinant human Epidermal Growth Factor (EGF) is a 6,200 Da protein containing 53 amino acid residues.
