proNGF Rapid ELISA Kit: Human (1 plate)


Catalogue No. BEK-2226-1P

Description The Biosensis proNGF RapidTM enzyme-linked immunosorbent assay (ELISA) Kit is a sandwich ELISA that allows the quantification of full-length proNGF protein in less than 4 hours in human serum, heparin-plasma, cell supernatants and lysates only if used as directed. Please refer to the kit protocol for specific use instructions for each substrate application.

This ELISA kit consists of a pre-coated anti-proNGF capture antibody, a biotinylated anti-proNGF 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 proNGF present in samples and protein standards. A human proNGF positive control (QC sample) is provided to assure consistent assay performance.

This proNGF ELISA kit contains a recombinant human proNGF standard expressed in E.coli. This ELISA kit does not cross-react with the mouse form of proNGF, and due to sequence homology of mouse and rat proNGF is not expected to detect rat proNGF. The antibodies used in this ELISA kit bind epitopes within the pro-domain of the protein and therefore recognize proNGF and the pro-domain peptide, but do not cross-react with mature NGF!

Note that accurate proNGF quantification in human serum requires the addition of Heterophilic Antibody Blocker BL-003-1000 provided in the kit, and available for purchase separately.

This kit has not been tested for other applications. Sufficient amount of proNGF standard is supplied to allow for spike- and recovery experiments in order to validate this ELISA assay for other sample matrices if required. This kit has been configured for research use only and is not to be used in diagnostic or clinical procedures.

Batch No. Refer to the product label.
Antigen Nerve growth factor (NGF) is synthesized as a precursor (proNGF) which may be released and have physiological functions to cause cell death. It binds neurotrophin receptor p75 and sortilin and may also be important for the development of nervous system. proNGF is synthesized in target tissues and glia, transported retrogradely and may be released.
