Biological Activity

Species: Human
Expression system: E.coli
Purity: > 95% as determined by reduced SDS-PAGE
Endotoxin: less than 0.001 ng/ug (0.01 EU/ug)
Storage and stability: Lyophilized proteins should be stored at < -20°C but can be stored at room temperature for up to 3 weeks. The recombinant protein solution can be stored at 4-7℃ for 2-7 days. The isometric solution of the recombinant sample was stable at < -20°C for 3 months.


Bioactivity: Neurotrophic factor-3 (NT-3) is a member of the NGF family of neurotrophic factors and is structurally related to β-NGF, BDNF and NT-4. NT3 cDNA encodes a precursor protein with 257 amino acid residues and a proprotein containing a signal peptide, which is cleaved to produce an NT3 mature protein with 119 amino acid residues. The amino acid sequence of mature human, mouse and rat NT-3 is identical. Nt-3 selectively promotes differentiation and survival of specific neuronal subsets in the central and peripheral nervous systems.

Chemical Information

Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.

Recombinant Human B2M Protein (Mammalian, C-6His)

β-2-Microglobulin (B2M) is a secreted protein with 1 Ig-like C1-type (immunoglobulin-like) domain which belongs to the beta-2-microglobulin family. B2M may adopt the fibrillar configuration of amyloid in certain pathologic states.

Recombinant Mouse E-Selectin/CD62E Protein (HEK293)

E-selectin, also known as endothelial leukocyte adhesion molecule-1 (ELAM-1) and CD62E, is an inducible adhesion molecule that is expressed on the surfaces of stimulated vascular endothelial cells and is sometimes involved in cancer cell metastasis.

Recombinant Human DPP4/CD26 (Mammalian, C-6His)

DPP4/CD26 is a signal-anchor for type II membrane protein that belongs to the peptidase S9B family. DPP4/CD26 acts as a positive regulator of T-cell coactivation, by binding at least ADA, CAV1, IGF2R, and PTPRC. It’s binding to CAV1 and CARD11 induces T-cell proliferation and NF-kappa-B activation in a T-cell receptor/CD3-dependent manner.

Recombinant Human USP14 (E.coli, N-6His)

USP14 belongs to the ubiquitin-specific processing (USP) family which is a deubiquitinating enzyme (DUB) with His and Cys domains. USP14 acts also as a physiological inhibitor of endoplasmic reticulum-associated degradation (ERAD) under the non-stressed condition by inhibiting the degradation of unfolded endoplasmic reticulum proteins via interaction with ERN1.

Recombinant Human EpCAM/Trop-1 (Mammalian, C-Fc)

Epithelial Cell Adhesion Molecule (EpCAM) is a signal type I transmembrane glycoprotein. EpCAM plays a role in embryonic stem cells proliferation and differentiation; it up-regulates the expression of FABP5, MYC and Cyclin A and Cyclin E. It is highly and selectively expressed by undifferentiated embryonic stem cells.
