| Preparation method | E. coli |
| Purity | > 92 % as determined by SDS-PAGE |
| Alternative | Epidermal Growth Factor; HOMG4; URG; Pro-epidermal growth factor; EGF |
| Formulation | Lyophilized from sterile PBS, pH 7.4 |
| Molecular weight | 6.3 kDa |
| Usage notes | Always centrifuge tubes before opening. It is recommended to reconstitute the lyophilized Human EGF protein in sterile ddH2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions. |
| Storage instructions | Lyophilized Human EGF proteinshould be stored desiccated below -20°C. Upon reconstitution, the protein should be stored at 4°C between 2-7 days and for future use below -20°C. For long term storage it is recommended to add a carrier protein (0.52% HSA or BSA). Please prevent freeze-thaw cycles. |
| Shipping | The product is shipped at ambient temperature. |

| Background | EGF is the founding member of the EGF-family of proteins. Members of this protein family have highly similar structural and functional characteristics. EGF contains 9 EGF-like domains and 9 LDL-receptor class B repeats. Human EGF is a 6045-Da protein with 53 amino acid residues and three intramolecular disulfide bonds. As a low-molecular-weight polypeptide, EGF was first purified from the mouse submandibular gland, but since then it was found in many human tissues including submandibular gland, parotid gland. It can also be found in human platelets, macrophages, urine, saliva, milk, and plasma. EGF is a growth factor that stimulates the growth of various epidermal and epithelial tissues in vivo and in vitro and of some fibroblasts in cell culture. It results in cellular proliferation, differentiation, and survival. Salivary EGF, which seems also regulated by dietary inorganic iodine, also plays an important physiological role in the maintenance of oro-esophageal and gastric tissue integrity. EGF acts by binding with high affinity to epidermal growth factor receptor on the cell surface and stimulating the intrinsic protein-tyrosine kinase activity of the receptor. The tyrosine kinase activity, in turn, initiates a signal transduction cascade that results in a variety of biochemical changes within the cell - a rise in intracellular calcium levels, increased glycolysis and protein synthesis, and increases in the expression of certain genes including the gene for EGFR - that ultimately lead to DNA synthesis and cell proliferation. |

1.The species of antibody reactivity should be the sample species that can be matched normally after Abbkine R&D experts have passed strict scientific verification. If your sample is not within the range of reactivity, in order to improve the efficiency and results of your experiment, it is not suggested to try other species. Otherwise, it may lead to sample mismatch and affect the effect of your experiment.
2.Please aliquot the antibody received as soon as possible and store it at -20℃, avoid repeated freezing and thawing, and use it within one year.
