Epithelial to mesenchymal transition (EMT) allows cancers to become invasive. To investigate EMT, a neural stem cell (NSC)-based in vitro model devoid of serum and enzymes is described. This standardized system allows quantitative and qualitative assessment of cell migration, gene and protein expression. The model is suited for drug discovery.

Analysis of tear film cytokines helps in studying various ocular diseases. Bead based multiplex assays are simple and sensitive and enable the testing of multiple targets in samples with small volumes. Here we describe a protocol for tear film cytokine profiling a using bead based multiplex assay.
