Proheparin-Binding EGF-like Growth Factor Human Recombinant ( HB-EGF Human )

Data sheet

Formulation

The protein was lyophilized from a concentrated (1mg/ml) solution containing 1xPBS pH-7.4.

Solubility

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

Purity

Greater than 97.0% as determined by:(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE.

Description

HB-EGF Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 86 amino acids and having a molecular mass of 9.7kDa.The HB-EGF is purified by proprietary chromatographic techniques.

Protein Background

HB-EGF is an EGF related growth factor which signals via the EGF receptor, and stimulates the proliferation of SMC (smooth muscle cells), fibroblasts, epithelial cells and keratinocytes. HB-EGF is expressed in various cell types and tissues, including vas

Expression host

Escherichia Coli.

Reagent Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.

Stability

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