The Biosensis NGF RapidTM enzyme-linked immunosorbent assay (ELISA) Kit is a sandwich ELISA that allows the quantification of human NGF in less than 3 hours in cell culture supernatants, serum, plasma (citrate) and brain extracts only if used as directed. Please refer to the kit protocol for specific use instructions for each substrate application, in particular serum and plasma samples.
This ELISA kit consists of a pre-coated mouse monoclonal anti-NGF capture antibody, a biotinylated anti-NGF detection antibody and horseradish peroxidase (HRP)-conjugated streptavidin. The addition of a substrate 3,3',5,5'-tetramethylbenzidine, TMB yields a colored reaction product which is directly proportional to the concentration of NGF present in samples and protein standards. A human NGF positive control (QC sample) is provided to assure consistent assay performance.
This NGF ELISA kit is designed to measure human NGF and thus employs a recombinant human NGF standard approved by the World Health Organization (WHO). Due to a high degree of NGF sequence homology, the antibodies used in this kit will also detect NGF from numerous other species including mouse and rat!
The antibodies used in this ELISA kit bind epitopes within the mature domain of the protein and therefore can recognize both the pro- and the mature form of NGF. However, internal validation data demonstrates <0.1% cross-reactivity (determined at 25 ng/mL, diluted in assay buffer) with human proNGF protein, suggesting the preferential quantification of mature NGF over full-length human proNGF
Note that accurate NGF quantification in human citrate-plasma requires the addition of Heterophilic Antibody Blocker BL-005-500 provided in the kit, and available for purchase separately.
This kit has not been tested for other applications. It has been configured for research use only and is not to be used in diagnostic or clinical procedures.

Application DetailsELISA. For the quantification of Nerve growth factor (Beta-NGF) in Culture Supernatant, Serum, Plasma (Citrate), Tissue Homogenates. Please download the detailed product insert for complete instructions for the successful use of this ELISA. Use only as directed.
TargetNerve growth factor (Beta-NGF)
Target Cross-Reactivity (ELISA)The antibodies used in this ELISA kit bind epitopes within the mature domain of the protein and therefore can recognize both the pro- and the mature form of NGF. However, human proNGF protein shows <0.1% cross-reactivity (determined at 25 ng/mL, diluted in assay buffer), suggesting the preferential quantification of mature NGF over full-length human proNGF.
This NGF ELISA does not cross-react with brain derived neurotrophic factor (BDNF), neurotrophin-3 (NT-3), NT-4/5, glial cell line-derived neurotrophic factor (GDNF) and vascular endothelial growth factor (VEGF165) tested at 25 ng/mL. Due to a high degree of NGF sequence homology, the antibodies used in this kit will also detect mature NGF from numerous other species including mouse and rat!

Scientific BackgroundFUNCTION: Nerve growth factor is important for the development and maintenance of the sympathetic and sensory nervous systems. It stimulates division and differentiation of sympathetic and embryonic sensory neurons. SUBUNIT: Homodimer, associated by non-covalent forces. SUBCELLULAR LOCATION: Secreted protein. SIMILARITY: Belongs to the NGF-beta family.
