Type:
Active Protein & In Stock Protein
Source:
E.Coli
Field of Research:
Cancer
Relevance:
Growth factor that mediates its effects via EGFR, ERBB2 and ERBB4. Required for normal cardiac valve formation and normal heart function. Promotes smooth muscle cell proliferation. May be involved in macrophage-mediated cellular proliferation. It is mitogenic for fibroblasts, but not endothelial cells. It is able to bind EGF receptor/EGFR with higher affinity than EGF itself and is a far more potent mitogen for smooth muscle cells than EGF. Also acts as a diphtheria toxin receptor.
Endotoxin:
Less than 1.0 EU/μg as determined by LAL method.
Purity:
>97% as determined by SDS-PAGE.
Activity:
Yes
Bioactivity:
Fully biologically active when compared to standard. The ED50 as determined by a cell proliferation assay using murine Balb/c 3T3 cells is less than 1 ng/ml, corresponding to a specific activity of > 1.0 x 106 IU/mg.
Form:
Lyophilized powder
Buffer:
Lyophilized from a 0.2 µm filtered 20 mM PB, pH 7.4, 130 mM NaCl
Reconstitution:
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.

Molecular Weight:
9.7 kDa
Storage Conditions:
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
