产品描述 Description
产品文档 Product Documents
Purity:>98%
Product Data
Purity
Greater than 95.0% as determined by:(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE.
Source
Chinese Hamster Ovary Cells.
Physical 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
Was analyzed by Mass spectrometry.
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 Nerve Growth Factor b although stable at room temperature for 3 weeks, should be stored desiccated below -18°C . Upon reconstitution Nerve Growth Factor-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 chick E9 DRG neurite outgrowth was found to be < 1.0 ng/ml, corresponding to a specific activity of > 1 x 106 units/mg.
Formulation
The protein was lyophilized from a 0.2µm filtered solution in 20mM PB and 250mM NaCl, pH 7.0.
