Opis ogólny
Recombinant, human epidermal growth factor (54 amino acids) expressed in E. coli. Identical to native human EGF except for an additional N-terminal methionine. Human EGF is 70% homologous to mouse EGF and has been shown to have similar biological activity. Mitogenic for a wide range of ectoderm- and endoderm-derived cells from tissue such as breast, cornea, epidermis, dermis, liver, pancreas, nerve, amnion, and adrenal medulla. Binding of EGF to its 170 kDa transmembrane receptor results in dimerization of the receptor, activation of the intrinsic receptor tyrosine kinase, and initiation of the complex signal transduction cascade that leads to cell proliferation and/or differentiation. Acts as a survival factor in preventing apoptosis.

Działania biochem./fizjol.
ED₅₀ = 100-400 pg/ml as measured by its ability to stimulate the ³H-thymidine incorporation in an EGF-responsive mouse fibroblast cell line, Balb/3T3.
Ostrzeżenie
Toxicity: Standard Handling (A)
Rekonstytucja
Following reconstitution, aliquot and freeze (-20°C or -70°C) for long term storage or refrigerate (4°C) for short-term storage. Avoid freeze/thaw cycles of solutions. Stock solutions are stable for up to 1 month at 4°C or for up to 3 months at -20°C or -70°C.
Reconstitute to a concentration of ≥10 µg/ml in 10 mM acetic acid containing ≥0.1% HSA or BSA.

In response to estrogens, estrogen receptor alpha (ERα), a critical regulator of homeostasis, is degraded through the 26S proteasome. However, despite the continued presence of estrogen before menopause, ERα protein levels are maintained. We discovered that ERK1/2-RSK2 activity oscillates during
