    Human Beta-NGF Protein, premium grade(BEF-H5214) is expressed from human 293 cells (HEK293). It contains AA Ser 122 - Ala 241 (Accession # P01138 ).
    Predicted N-terminus: Ser 122
    It is produced under our rigorous quality control system that incorporates a comprehensive set of tests including sterility and endotoxin tests. Product performance is carefully validated and tested for compatibility for cell culture use or any other applications in the early preclinical stage. When ready to transition into later clinical phases, we also offer a custom GMP protein service that tailors to your needs. We will work with you to customize and develop a GMP-grade product in accordance with your requests that also meets the requirements for raw and ancillary materials use in cell manufacturing of cell-based therapies.
  • Molecular Characterization
    Beta-NGF Structure

    This protein carries no "tag".

    The protein has a calculated MW of 13.5 kDa. The protein migrates as 14-15 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Endotoxin
    Less than 0.01 EU per μg by the LAL method.
  • Sterility
    The sterility testing was performed by membrane filtration method.
  • Mycoplasma
  • Purity

    >90% as determined by SDS-PAGE.

    >90% as determined by SEC-MALS.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in 20 mM NaAC, 150 mM NaCl, pH5.5 with trehalose as protectant.

    Contact us for customized product form or formulation.

  • Reconstitution

    Please see Certificate of Analysis for specific instructions.

    For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.

  • Background
    Nerve growth factor beta (beta-NGF) is a neurotrophic factor that plays critical role in the development and maintenance of sensory and sympathetic neurons. The active form of human beta-NGF is is a noncovalently disulfide-linked homodimer, which is secreted and signals through the low affinity nerve growth factor receptor (LNGFR) and the tropomyosin receptor kinase A (TrkA) to activate PI3K, Ras, and PLC signaling pathways.
