Description

Heparin-binding epidermal growth factor (HB-EGF)-like growth factor (EGF) is found in cerebral neurons. Human HB-EGF- shares 76% and 73% aa sequence identity with rat and mouse HB-EGF. Its expression is increased after hypoxic or ischemic injury, which also stimulates neurogenesis. HB-EGF has been implicated as a participant in a variety of normal physiological processes such as blastocyst implantation and wound healing, and in pathological processes such as tumor growth, SMC hyperplasia and atherosclerosis. The protein is an 86 amino acid mitogenic and chemotactic glycoprotein containing an EGF-like domain with six conserved cysteine residues.

Molecular Weight

Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.

Purity

>97% by SDS-PAGE and HPLC analyses.

Biological Activity

The ED50 as determined by a cell proliferation assay using mouse Balb/c 3T3 cells is less than 1 ng/mL, corresponding to a specific activity of > 1.0 × 106 IU/mg. Fully biologically active when compared to standard.

Endotoxin

< 1.0 EU per 1μg of the protein by the LAL method.

Formulation

Lyophilized from a 0.2 μm filtered concentrated solution in 10 mM PB, 500 mM NaCl, pH7.4.

Reconstitution

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/ml. Stock solutions should be apportioned into working aliquots and stored at ≤ -20℃. Further dilutions should be made in appropriate buffered solutions.

Note
