CHEMICON's NS220 Neurite Outgrowth Assay Kit (3 µm) utilizes microporous tissue culture insert technology from EMD Millipore and is based on the use of Millicell cell culture inserts (chambers) containing a permeable membrane with 3-μm pores at the base. The Millicell inserts utilized in this kit are appropriate for cells projecting neurites of up to 3 µm diameter, e.g. N1E-115 cells [Abe et al., 2003], Dorsal Root Ganglia and Schwann cells [Windebank et al., 1985].
The assay is a simple, efficient, and versatile system for the quantitative determination of compounds that influence neurite formation and repulsion. With this system, it is possible to screen numerous biological and pharmacological agents simultaneously, directly evaluate adhesion and guidance receptor functions responsible for neurite extension and repulsion, as well as analyze gene function in transfected cells. The microporous filter allows for biochemical separation and purification of neurites and cell bodies for detailed molecular analysis of protein expression, signal transduction processes and identification of drug targets that regulate neurite outgrowth or retraction processes. Reagents and materials supplied in the NS220 Neurite Outgrowth Assay Kit are sufficient for 12 tests.
