Rat 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 RapidTM enzyme-linked immunosorbent assay (ELISA) Kit is a sandwich ELISA that allows the quantification of rat NGF in less than 3 hours in cell culture supernatants, serum, and brain extracts. This NGF ELISA kit is designed to measure rat NGF and thus employs a recombinant rat NGF protein. Due to a high degree of NGF sequence homology, the antibodies used in this kit will also detect NGF from other species including human and mouse.

The antibodies used in this ELISA kit bind epitopes within the mature domain of the protein. No cross-reactivity was observed with brain derived neurotrophic factor (BDNF), neurotrophin-3 (NT-3), NT-4/5 and proNGF protein tested at 25 ng/mL in assay buffer. Due to a high degree of NGF sequence homology, the antibodies used in this kit will also detect NGF from other species including human and mouse. Mature NGF (27 kDa) and full-length proNGF (50 kDa) were assayed in parallel at equimolar protein concentrations across the NGF ELISA calibration range (3.9-250 pg/mL; 0.14-9.2 pmol/L) . OD readings for proNGF were indistinguishable from the assay's blank OD readings. Data was obtained with the Mouse NGF ELISA kit (BEK-2213) which uses the same assay capture and detection antibodies.
