beta-NGF is a neurotrophic factor found in many tissues and is involved in a range of biological activities such as embryonal development, survival, and regeneration of mammalian sympathetic and sensory neuron.
It is also involved in the immune system and has been shown to downregulate IFN-gamma production by T-cells.
Also implicated in survival and regeneration of neurons.
NGF-beta and BDNF affect neural stem cells (NSC) proliferation and differentiation.
ED50 = 1.3-2 µg/ml (determined by stimulation of proliferation of TF-1 cells and is typically <1.0 ng/ml, corresponding to a specific activity of >1,000,000units/mg.
Solubility & Handling
Storage instructions
-20°C
Solubility overview
To make a stock solution, reconstitute in sterile 18MΩcm water at a concentration > 100μg/ml, which can then be diluted to make a working solution
Handling
Solutions should be made in sterile deionized water (not less than 100 µg/ml). This solution can then be further diluted with other aqueous solutions.
Following reconstitution, solutions may be stored at 4°C and are useable for around 2-7 days and for future use store at -18°C.
For long term storage, a carrier protein (0.1% HSA or BSA) should be added to stock solutions. Solutions should be aliquoted into tightly sealed vials for storage at -20°C. Freeze-thaw cycles should be prevented.
