| Purity | Greater than 95.0% as determined by SDS-PAGE. | Source | Escherichia Coli. |
| Phycical Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. | Shipping Condition | Shipped at Room temp. |
| Synonyms | Beta Polypeptide; NGF; NGFB; HSAN5; Beta-NGF; MGC161426; MGC161428. | ||
| Amino Acid Sequence | MSSSHPIFHRG EFSVCDSVSV WVGDKTTATD IKGKEVMVLG EVNINNSVFK QYFFETKCRD PNPVDSGCRG IDSKHWNSYC TTTHTFVKAL TMDGKQAAWR FIRIDTACVC VLSRKAVRRA. | ||
| Solubility | It is recommended to reconstitute the lyophilized NGF-b in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions. | ||
| Stability | Lyophilized Beta-NGF although stable at room temperature for 3 weeks, should be stored desiccated below -18°C . Upon reconstitution NGF-Beta 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 (0.1% HSA or BSA).Please prevent freeze-thaw cycles. | ||
| Biological Activity | The ED50, calculated by its ability to stimulate proliferation of TF-1 cells and is typically < 1.0 ng/ml, corresponding to a specific activity of > 1,000,000units/mg. | ||
| Formulation | The beta-NGF protein was lyophilized from a 0.2µm filtered solution containing 0.1% Trifluoroacetic Acid (TFA). | ||
NGF-beta has nerve growth stimulating activity and the complex is involved in the regulation of growth and the differentiation of sympathetic and certain sensory neurons. Mutations in this gene have been associated with hereditary sensory and autonomic neuropathy, type 5 (HSAN5), and dysregulation of this gene's expression is associated with allergic rhinitis.
The ED50, calculated by its ability to stimulate proliferation of TF-1 cells and is typically < 1.0 ng/ml, corresponding to a specific activity of > 1,000,000units/mg.
