| Species | Human | |
| Protein Construction |
|
|
| Purity | > 95% as determined by Bis-Tris PAGE | |
| Endotoxin Level | Less than 1EU per μg by the LAL method. | |
| Biological Activity | Measured in a cell proliferation assay using TF?1 human erythroleukemic cells. Test result was comparable to standard batch. | |
| Expression System | HEK293 | |
| Theoretical Molecular Weight | 13.49 kDa | |
| Apparent Molecular Weight | Due to glycosylation, the protein migrates to 14-18 kDa based on Bis-Tris PAGE result. | |
| Formulation | Lyophilized from 0.22 μm filtered solution in 20mM NaAc, 150mM Nacl (pH 5.5). Normally 8% trehalose is added as protectant before lyophilization. | |
| Reconstitution | Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in 20mM NaAc, 150mM Nacl (pH 5.5) | |
| Storage & Stability | Upon receiving, the product remains stable up to 6 months at -20 °C or below. Upon reconstitution, the product should be stable for 3 months at -80 °C. Avoid repeated freeze-thaw cycles. |
| Target Background | Nerve growth factor-beta (β-NGF) is a polypeptide growth factor that regulates survival, growth, and differentiation of specific peripheral and central neurons via its high-affinity receptor, tyrosine kinase receptor A (TrKA), and low-affinity receptor, p75 neurotrophin receptor (p75NTR). |
| Synonyms | NGF; NGFB; Beta NGF; HSAN5; |
