Intra-assay Precision (Precision within an assay): CV%<8% | ||||||
Three samples of known concentration were tested twenty times on one plate to assess. | ||||||
Inter-assay Precision (Precision between assays): CV%<10% | ||||||
Three samples of known concentration were tested in twenty assays to assess. |
To assess the linearity of the assay, samples were spiked with high concentrations of human NGF in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay. | ||||||

The HumanNGF ELISA kit is designed for the detection and quantification of human NGF in serum, plasma, cell culture supernates, tissue homogenates, and cell lysates. Many performances including specificity, sensitivity, precision, linearity, and recovery of this kit, have been rigorously tested. More validation information is elucidated in the product instructions. The NGF in the sample or standard is immobilized on the pre-coated NGF antibody and then sandwiched by Biotin-conjugated NGF antibody. The forming Ag-Ab-Ag immune complex is labeled by HRP-avidin and develops a color reaction upon adding TMB substrate solution. The color intensity is positively correlated to the amount of NGF bound in the initial step and can be measured at 450 nm via a microplate reader.
NGF is a neurotrophic factor essential for the growth, differentiation, and survival of sympathetic and sensory afferent neurons during development. It contributes to neuronal phenotype by regulating axonal guidance, gene transcription, neurotransmitter release, and synaptic plasticity. Numerous studies have shown that NGF plays a pivotal role in the modulation of nociception in adulthood. There are two receptors for NGF: p75 neurotrophin receptor (p75NTR) and tropomyosin receptor kinase A (TrkA). A study demonstrated that NGF-TrkA signaling-mediated communication between osteoblasts and sensory nerves is essential for load-induced bone formation in mice.

How does conducting the analysis from serum or plasma differ? Does it affect the accuracy of the results? When analyzing, is it enough to run the test once? Or does it need to be repeated 3 times?
