TF-1 Cell Proliferation Assay Method for Estimating Bioactivity of Nerve Growth Factor

<p>Nerve growth factor (NGF) is a neurotrophic factor responsible for the differentiation and survival of sympathetic and sensory neurons as well as selective populations of cholinergic neurons. The MTT assay is to add the chromogenic substance MTT after the NGF has stimulated the TF1 cells, to conduct a colorimetric analysis on the micro plate reader, then to compare the results with a standard curve to arrive at the biological activity of the test substance. To use the MTT assay to measure the biological activity of the NGF, it is easy to handle, with good and reliable results, repeatable and with no impact of the human factors.</p>
