Available Options

Select the variant that best fits your experiment. Availability and lead time may vary by option.

  • Options: Size (3) — 2 ug, 10 ug, 1 mg
  • Lead time: options listed as “in stock at manufacturer” typically ship in 5–7 business days; other statuses may take longer.
  • Storage: Lyophilized NGF2 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution NGF-2 should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.
  • Shipping: cold-chain shipment (typically with ice packs).
  • Upon receipt: store at the recommended temperature as soon as possible.
  • Sales terms and conditions: Please review prior to ordering.

Target NEUROTROPHIN-3

Recombinant Human Neurotrophin-3 is supplied as a recombinant protein for in vitro research use.

Background

NT3 a member of the neurotrophin family, that controls survival and differentiation of mammalian neurons. This protein is closely related to both nerve growth factor and brain-derived neurotrophic factor. It may be involved in the maintenance of the adult nervous system, and may affect development of neurons in the embryo when it is expressed in human placenta. 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.

Product format

Provided as a recombinant protein suitable for in vitro workflows such as binding studies, screening, and assay development. Refer to the specifications table for expression format and molecular properties.

Quality notes

Protein quantitation was carried out by two independent methods:
1. UV spectroscopy at 280 nm using the absorbency value of 2.165 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics).
2. Analysis by RP-HPLC, using a standard solution of NT-3 as a Reference Standard.

What is the purity of Recombinant Human Neurotrophin-3 (Human)?
Greater than 95.0% as determined by analysis by SDS-PAGE. BioHippo includes a Certificate of Analysis (CoA) confirming purity per lot with every order.
What buffer / formulation is this protein supplied in?
Supplied as: Lyophilized from 0.1% TFA. Reconstitute lyophilized material in sterile ultrapure water or the recommended buffer per the datasheet prior to use.
How should Recombinant Human Neurotrophin-3 (Human) be stored?
Lyophilized NGF2 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution NGF-2 should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles. Prepare single-use aliquots after reconstitution to avoid repeated freeze–thaw cycles.
What expression system was used to produce this protein?
This recombinant protein was expressed in E. coli. The system was selected to achieve high yield, correct folding, and appropriate post-translational modifications.
Is this protein biologically active?
The ED 50 as determined by the dose-dependent proliferation of neuroblastoma cell line expressing BR6 is 3.49 ng/ml. Refer to the product datasheet for recommended assay conditions and controls.
Is this protein approved for clinical or in vitro diagnostic use?
No. Supplied for Research Use Only (RUO) — not intended for therapeutic applications or in vitro diagnostic procedures.
Can I request a custom size, tag variant, or formulation?
Yes. BioHippo can accommodate custom requests including alternative sizes, His/GST/Fc tag variants, bulk quantities, and custom formulations. See the Customization & Add-ons tab or email support@biohippo.com.
