Epidermal Growth Factor Rat Recombinant ( EGF Rat )

Data sheet

Formulation

The protein was lyophilized from a concentrated (1mg/ml) solution containing 0.01M sodium acetate buffer.

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 99.0% as determined by(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE.

Description

Epidermal Growth Factor Rat purified from submandibular gland is a single, glycosylated, polypeptide chain having a molecular mass of 6.15 kDa.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

Adult Male Rat Submandibular Glands.

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
