Epidermal Growth Factor Human Recombinant, Pichia ( EGF Human, Pichia )

Data sheet

Formulation

Each lyophilized mg contains 0.15M NaCl, 0.025M sodium bicarbonate, pH-7.5.

Solubility

It is recommended to reconstitute the lyophilized Epidermal Growth Factor in sterile 18M-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.

Purity

Greater than 95.0% as determined by(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE.

Description

Epidermal Growth Factor Human Recombinant produced in Pichia Pastoris is a single, glycosylated, polypeptide chain containing 51 amino acids and having a molecular mass of 6KDa.The EGF is purified by proprietary chromatographic techniques.

Protein Background

Epidermal growth factor has a profound effect on the differentiation of specific cells in vivo and is a potent mitogenic factor for a variety of cultured cells of both ectodermal and mesodermal origin. The EGF precursor is believed to exist as a membrane-

Expression host

Pichia Pastoris.

Synonyms

Urogastrone, URG, EGF.

Reagent Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.

Stability

Lyophilized Epidermal Growth Factor Recombinant although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution EGF should be stored at 4°C between 2-7 days and for future use below -18°C.For long term storage

Amino acid sequence

The sequence of the first five N-terminal amino acids was determined and was found to be Asn-Ser-Asp-Ser-Glu, which agrees with the sequence of native EGF human.N-terminal methionine has been completely removed enzymatically.

Biological Activity

The ED50, calculated by the dose-dependant proliferation of murine BALB/c 3T3 cells (measured by 3H-thymidine uptake) is
