Human EGF/重组人表皮生长因子
产品编号:100-009/ 100-008
产品规格:500μg/100μg
Description: Recombinant human Epidermal Growth Factor (EGF) produced in E. coli is a single, non-glycosylated polypeptide chain containing 53 amino acids and having a molecular mass of 6.2 kDa. EGF stimulates the proliferation of a wide range of epidermal and epithelial cells.
Source: E. coli
Molecular Weight: 6.2 kDa
Purity: > 98% by RP-HPLC, Anion-exchange FPLC, Silverstain
Endotoxin level/内毒素水平: < 0.1 ng per μg (IEU/μg) of rh EGF
Stabilizer: none
Formulation: lyophilized
Biological Activity: The , determined by the dose-dependent stimulation of 3H-thymidine uptake of murine Balb/c 3T3 cells is < 0.1 ng/ml.
Reconstitution: The lyophilized rh EGF is soluble in water and most aqueous buffers. The lyophilized EGF can be reconstituted in sterile water to a concentration not less than 0.1 mg/ml.
Stability: The lyophilized human rh EGF stable at room temperature for 3 weeks, should be best stored desiccated at -20°C. Reconstituted rh EGF should be stored at 4°C between 2-7 days and in working aliquots at –20oC. For long term storage it is recommended to add a carrier protein (0.1% HAS or BSA). Avoid repeated freeze-thaw cycles.
Usage: Human EGF is offered for research use. Not for drug use. Not for human use.
