蛋白结构（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.
内毒素（Endotoxin）
Less than 0.01 EU per μg by the LAL method.
纯度（Purity）
>90% as determined by SDS-PAGE.
>95% as determined by SEC-HPLC.
制剂（Formulation）
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

电泳（SDS-PAGE）
Human NT-3 Protein, Tag Free on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 90% (With Star Ribbon Pre-stained Protein Marker).
SEC-HPLC
The purity of Human NT-3 Protein, Tag Free (Cat. No. NT3-H5213) was greater than 95% as determined by SEC-HPLC.
活性（Bioactivity）-ELISA
Immobilized Human NT-3 Protein, Tag Free (Cat. No. NT3-H5213) at 1 μg/mL (100 μL/well) can bind Human TrkC Protein, Fc Tag (Cat. No. TRC-H5256) with a linear range of 0.8-13 ng/mL (QC tested).
Protocol
背景（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 cytoki.
