Human Beta-NGF Rapid ELISA Assay

FUNCTION: 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.

The Biosensis NGF Rapid 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 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, 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.
