Description
This Human Neurotrophin-4 ELISA Kit is intended for quantitative detection of human NT-4 in cell culture supernates and serum. Strip well format. Reagents for up to 96 tests.
This human NT-4 ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from mouse specific for NT-4 has been precoated onto 96-well plates. Standards (sf21, G81-A210) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for NT-4 is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the human NT-4 amount of sample captured in plate.
The capture antibody is a monoclonal antibody from mouse, the detection antibody is a biotinylated polyclonal antibody from goat. Expression system for standard: Neurotrophin-4 (NT-4), also known as neurotrophin-5 (NT-5), is a protein that in humans is encoded by the NTF4 gene. Human NT-4 as well as a human NT-4 pseudogene colocalize to chromosome 19 band q13.3. NT-4 is a member of a family of neurotrophic factors, the neurotrophins, that control survival and differentiation of vertebrate neurons (2-4). NT-4 is a neurotrophic factor that signals predominantly through the TrkB receptor tyrosine kinase. NT4 plays a physiological role essential for hippocampus- and amygdala-dependent long-term memory and hippocampal long-lasting LTP and that NT4 may be useful in the therapy of acquired disorders of learning and memory
