ProSpec-HB-EGF Mouse

DTR, HEGFL, diphtheria toxin receptor, DTSF.

HB-EGF is an EGF related growth factor which signals via the EGF receptor, and stimulates the proliferation of SMC , fibroblasts, epithelial cells and keratinocytes. HB-EGF is expressed in various cell types and tissues, including vascular endothelial cells and SMC, macrophages, skeletal muscle, keratinocytes and particular tumor cells. HB-EGF’s ability to explicitly bind sulfate proteoglycans is dissimilar from other EGF-like molecules, and might be related to the enhanced mitogenic activity, relative to EGF, that HB-EGF exerts on smooth muscle cells.

HB-EGF Mouse Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 86 amino acids and having a molecular mass of 9.8 kDa.
The HB-EGF is purified by proprietary chromatographic techniques

Escherichia Coli.

Sterile Filtered White lyophilized powder.

The protein was filtered and lyophilized from a concentrated solution containing 10mM PB and 500mM NaCl, pH7.4.

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

Lyophilized Mouse 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 recommended to add a carrier protein .
Please prevent freeze-thaw cycles.

Greater than 97.0% as determined by:
Analysis by RP-HPLC.
Analysis by -PAGE.
