Assay Principle
This sandwich ELISA quantifies mouse beta-nerve growth factor (gene Ngf) in cell culture supernatants and serum. Strips are pre-coated with a capture antibody. After the sample is added, a biotinylated detection antibody binds the captured protein, and an avidin–biotin–peroxidase complex supplies the enzyme. TMB develops color in proportion to the bound target; the reaction is stopped and read at 450 nm, and concentrations are read from the standard curve.
Nerve growth factor (NGF) is the founding member of the neurotrophin family. Acting through its high-affinity receptor TrkA (NTRK1) and p75NTR (NGFR), it supports survival and growth of sympathetic and sensory neurons, while its precursor proNGF can signal cell death through p75NTR and sortilin family co-receptors; NGF is also a major mediator of pain.
