Neurons and glia in neural tissue or cultures are commonly visualized and identified by immunodetection of cell-specific antigenic markers, including transcription factors, enzymes, cytoskeletal proteins, cell surface proteins, and secreted factors. The Bio-Techne brands R&D Systems and Novus Biologicals together offer an unparalleled selection of antibodies directed against these intracellular and cell surface proteins that can be used for the identification and characterization of different neural cell types. R&D Systems also offers a variety of different immunoassays, including the gold standard Quantikine ELISA Kits, for detecting secreted molecules. The Bio-Techne brand Tocris offers a novel and exclusive collection of tools, including bioactive small molecules, caged compounds, and fluorescent probes, for the functional identification of neural cells.
