★ product description
recombinant human epidermal growth factor (egf) is a biologically active protein factor for cell culture. it has a profound effect on the differentiation of specific cells in vivo, and is a powerful mitotic factor for a variety of ectoderm and mesoderm cells cultured in vitro.
this product is a lyophilized powder prepared by recombinant yeast, freeze-dried by multi-step separation and purification, and can be widely used in cell culture.
★ product features
l no animal origin: the product is free of animal virus, no pathogenic substances, no external factor pollution, and high safety.
l high purity: sds-page electrophoresis purity reaches 98%.
l high specific activity: biological activity per 1mg protein is 1.2×106u~2.0×106u. small amount of protein can achieve the desired experimental results.
l quality stability: this product is a lyophilized powder containing bioactive protective agent. it has been mass-produced and the difference between batches is small.

biological activity: according to chinese pharmacopoeia 2015 edition,it can use egf to stimulate balb/3t3 to test the biological activity .
★ product application
it can be used for cell culture to enhance cell proliferation, cell growth and cell differentiation.
★ usage method
l it is recommended to centrifuge the powder to the bottom of the tube before opening the lid, then dissolve it in sterilized deionized water to prepare a storage solution of 100μg/ml. it can be stored stably for 2 weeks at 2°c~8°c. when diluted to a lower concentration (not less than 10 μg/ml), 0.1% bsa or hsa is required. if it is necessary to extend the storage time, it is recommended to freeze at -70 ° c or -20 ° c. it is not recommended to repeat freezing and thawing.
l this product is for research use only. not for animals and humans
★ transportation and storage stability
l transport stability:it is transported in an ice pack to keep it active.
l storage stability:it is stored at -15 ° c to -20 ° c and can be stable for 24 months..
