Human HB-EGF was initially identified as a protein of 22 kD secreted by macrophage-like U937 cells. It belongs to the EGF family of proteins that includes EGF, TGF-α, heparin-binding EGF-like growth factor (HB-EGF), epigen, epiregulin, betacellulin, neuroregulin, and tomoregulin. All the EGF family members are synthesized as type I membrane protein precursors, which can undergo proteolytic cleavage at the plasma membrane to release a mature soluble ectodomain. It has been suggested that various metalloproteinases participate in the shedding of HB-EGF, such as MMP-3, MMP-7, ADAM9, ADAM10, ADAM12, and ADAM17. The ectodomain shedding is stimulated by phorbol esters, calcium ionophore, lysophosphatidic acid, and IL-1β. In addition, nardilysin, a metalloendopeptidase of the M16 family, binds HB-EGF and enhances its shedding through activation of TACE (ADAM17). The membrane-anchored HB-EGF acts in cell-cell and cell-extracellular matrix interactions; in addition, the membrane HB-EGF is the receptor for diphtheria toxin that can be internalized and induce apoptotic death. HB-EGF plays a crucial role in cardiac valvulogenesis; newborn knockout mice have malformed semilunar and atrioventricular heart valves and poorly differentiated lungs. HB-EGF is overexpressed in several types of cancer such as pancreatic carcinoma, ovarian cancer, and gastric carcinoma. Also, HB-EGF is involved in cancer metastasis and invasion of ovarian cancer, head and neck cancer, and thyroid carcinoma cells.

Molecular Mass
The 86 amino acid recombinant protein has a predicted molecular mass of approximately 9.76 kD. The DTT-reduced and non-reduced protein migrates at approximately 10 kD and 14.4 kD respectively by SDS-PAGE. The predicted N-terminal amino acid is Asp.
>98%, as determined by Coomassie stained SDS-PAGE.
0.22 µm filtered protein solution is in PBS pH 7.2
Endotoxin Level
Less than 0.1 EU per µg protein as determined by the LAL method.
10-25 µg sizes are bottled at 200 µg/mL.
Storage & Handling
Unopened vial can be stored between 2°C and 8°C for up to 2 weeks, at -20°C for up to six months, or at -70°C or colder until the expiration date. For maximum results, quick spin vial prior to opening. The protein can be aliquoted and stored at -20°C or colder. Stock solutions can also be prepared at 50 - 100 µg/mL in appropriate sterile buffer, carrier protein such as 0.2 - 1% BSA or HSA can be added when preparing the stock solution. Aliquots can be stored between 2°C and 8°C for up to one week and stored at -20°C or colder for up to 3 months. Avoid repeated freeze/thaw cycles.
Mouse HB-EGF induces the proliferation of of mouse BALB/3T3 cells in a dose-dependent manner. The ED50 for this effect is 0.6 - 3 ng/mL.


Application Notes

BioLegend carrier-free recombinant proteins provided in liquid format are shipped on blue ice. Our comparison testing data indicates that when handled and stored as recommended, the liquid format has equal or better stability and shelf-life compared to commercially available lyophilized proteins after reconstitution. Our liquid proteins are verified in-house to maintain activity after shipping on blue ice and are backed by our 100% satisfaction guarantee. If you have any concerns, contact us at

How does the activity of your recombinant proteins compare to competitors?

We quality control each and every lot of recombinant protein. Not only do we check its bioactivity, but we also compare it against other commercially available recombinant proteins. We make sure each recombinant protein’s activity is at least as good as or better than the competition’s. In order to provide you with the best possible product, we ensure that our testing process is rigorous and thorough. If you’re curious and eager to make the switch to BioLegend recombinants, contact your sales representative today!

What is the specific activity or ED50 of my recombinant protein?

The specific activity range of the protein is indicated on the product datasheets. Because the exact activity values on a per unit basis can largely fluctuate depending on a number of factors, including the nature of the assay, cell density, age of cells/passage number, culture media used, and end user technique, the specific activity is best defined as a range and we guarantee the specific activity of all our lots will be within the range indicated on the datasheet. Please note this only applies to recombinants labeled for use in bioassays. ELISA standard recombinant proteins are not recommended for bioassay usage as they are not tested for these applications.

Have your recombinants been tested for stability?

Our testing shows that the recombinant proteins are able to withstand room temperature for a week without losing activity. In addition the recombinant proteins were also found to withstand four cycles of freeze and thaw without losing activity.

Does specific activity of a recombinant protein vary between lots?

Specific activity will vary for each lot and for the type of experiment that is done to validate it, but all passed lots will have activity within the established ED50 range for the product and we guarantee that our products will have lot-to-lot consistency. Please conduct an experiment-specific validation to find the optimal ED50 for your system.

How do you convert activity as an ED50 in ng/ml to a specific activity in Units/mg?

Use formula Specific activity (Units/mg) = 10^6/ ED50 (ng/mL)
