The Next Secrets For Duvelisib
9 ?M) [16]. Taken together, these results confirm the potential for the dye-based plate reader approach described in this report to enable rapid approximations of neurite outgrowth and cell viability. CONCLUSION In summary, although imaging-based approaches to monitoring neurite outgrowth can provide detailed analyses of a number of features (e.g., number of extensions, branch points, and neurite lengths), these methods typically involve extensive time and labor to prepare samples, then PRDX4 image and analyze them. Here we report the development of a quick and simple indirect method for simultaneously measuring neurite outgrowth (via a cell membrane stain) and cell health (via a cell-permeable esterase substrate) in the same sample. This simple dual-color, dye-based staining method is not only suitable for microscopic visualization, but also enables rapid, unbiased microplate reader quantification. Here we described examples from testing this approach with mono-cultures (PC-12 derived Neuroscreen-1 cells) and two cultures (isolated rat cortex neurons and iPSC-derived iCell Neurons) that are highly enriched for neuronal cells. However, it is important to point out that since the dyes used in this approach are not neuron-specific this approach is not recommended for measuring neurite outgrowth in highly heterogeneous, mixed cultures of neuronal cells with other cell types. Instead, neurite outgrowth detection methods Duvelisib cell line that stain for specific neuronal markers (e.g., beta-III tubulin or MAP2) should be used for mixed cultures, as well as for confirmation studies when applying nonspecific reporters such as the dyes described Bleomycin in vitro in this work. Nevertheless, because the assay approach described here (to report on neurite outgrowth and neural cell viability) is non-specific, one can envision that this same reporter dye combination could be useful for indirectly measuring additional cellular processes that affect changes in cell membrane content and/or cell viability.
