Summary: Cat. No.: NT3-20H Product Overview: Recombinant Human neurotrophin 3 encoding the mature human NT-3 (Tyr129- Thr257) with 6 His tag on the N-Terminus was expressed inE. Coli. This protein was purified by Ni-NTA column. MW=16 KD. Description: Neurotrophin-3 is a protein that in humans is encoded by the NTF3 gene. The protein encoded by this gene, NT-3 is a neurotrophic factor, in the NGF (Nerve Growth Factor)-family of neurotrophins. It is a protein growth factor which has activity on certain neurons of the peripheral and central nervous system; it helps to support the survival and differentiation of existing neurons, and encourages the growth and differentiation of new neurons and synapses.
