    Product Description

     

    NGF was composed of three non-covalently linked subunits, alpha, beta, and  gamma. Both the alpha and  gamma subunits of NGF are members of the kallikrein family of serine proteases while the beta  subunit, called beta -NGF or 2.5S NGF, exhibits all the biological activities ascribed to NGF. The human protein shares approximately 90% homology at the amino acid level with both the mouse and rat beta -NGF and exhibits cross-species activity. NGF is a well-characterized neurotropic protein that plays a critical role in the development of sympathetic and some sensory neurons in the peripheral nervous system. In addition, NGF can also act in the central nervous system as a trophic factor for basal forebrain cholinergic neurons. NGF is mitogenic for a factordependent human erythroleukemic cell line, TF-1. NGF has been found to increase the number of mast cells in neonatal rats and to induce histamine release from peritoneal mast cells. NGF will enhance histamine release and strongly modulate the formation of lipid mediators by basophils in response to various stimuli. NGF will also induce the growth and differentiation of human B lymphocytes as well as suppress apoptosis of murine peritoneal neutrophils. These results, taken together, suggest that NGF is a pleiotropic cytokine which, in addition to its neurotropic activities, may have an important role in the regulation of the immune system.

    Tag

    None

    Physical Appearance

    Sterile Filtered White lyophilized (freeze-dried) powder.

    Purity

    > 95% by SDS-PAGE.

    Biological Activity

    Measured in a cell proliferation assay using TF-1 human erythroleukemic cells. The ED50 for this effect is typically 5-20 ng/mL.

    Endotoxin

    < 1.0 EU per 1μg of the protein by the LAL method.

    Formulation

    Lyophilized from a 0.2 μm filtered concentrated solution in PBS, pH 7.4.

    Reconstitution

    We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20°C. Further dilutions should be made in appropriate buffered solutions.

     

    Shipping and Storage

     

    The products are shipped with ice pack and can be stored at -20℃ to -80℃ for 1 year.

    Recommend to aliquot the protein into smaller quantities when first used and avoid repeated freeze-thaw cycles.


    Cautions

     

    1. Avoid repeated freeze-thaw cycles.

    2. For your safety and health, please wear lab coats and disposable gloves for operation.

    3. For research use only.
