Source
Human NT-3 Protein, Tag Free (NT3-H5213) is expressed from human 293 cells (HEK293). It contains AA Tyr 139 - Thr 257 (Accession # P20783).
Predicted N-terminus: Tyr 139
Molecular Characterization
This protein carries no "tag".
The protein has a calculated MW of 13.6 kDa. The protein migrates as 13-14 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
Endotoxin
Less than 0.01 EU per μg by the LAL method / rFC method.
Purity
>90% as determined by SDS-PAGE.
>95% as determined by SEC-HPLC.
Formulation
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

Background
Neurotrophin-3 (NT-3), encoded by the NTF3 gene, is a member of the NGF family of neurotrophic factors (also named neurotrophins). The neurotrophin family is comprised of at least four proteins including NGF, BDNF, NT-3, and NT-4/5. These secreted cytokines are synthesized as prepropeptides that are proteolytically processed to generate the mature proteins. Their functions including supporting the survival and differentiation of existing neurons, encouraging the growth and differentiation of new neurons and synapses, are required in both the central and the peripheral nervous systems. NT-4 signals predominantly through the TrkB receptor tyrosine kinase. NTF3-deficient mice generated by gene targeting display severe movement defects of the limbs. The mature peptide of this protein is identical in all mammals examined including human, pig, rat and mouse.
