|
Use/Stability: | Lyophilized protein is stable for 2-3 weeks when stored at room temperature and for 6-9 months when stored at -20°C.Reconstituted protein is stable for up to 1 week when stored at +4°C and for 4-6 weeks when stored at -80°C. |
|
Handling: | Avoid freeze/thaw cycles. |
|
Scientific Background: | Human β-NGF is responsible for survival, differentiation and maturation of sympathetic and sensory neurons. |
|
Regulatory Status: | RUO - Research Use Only |
|
Figure: Neurite outgrowth in PC12 cells.
Method: PC12 cells were grown on collagen coated 24-well plates in DMEM medium supplemented with 6% fetal calf serum and 6% horse serum for 24 hours. β-Nerve Growth Factor (human) (rec.) (Prod. No.
ALX-521-005) was addded at the indicated concentrations. The culture media was changed every 2-3 days. The development of neurites over a period of 5 days was visualized by methylene blue staining."
