Neuronal polarity is essential for the proper development, growth, and physiology of neurons. Within neurons, microtubules (MTs) and motor protein polarities are required for establishing and maintaining neuronal polarity. However, unanswered questions remain: 1. Why are some cytoplasmic molecules in axons but not dendrites? 2. How do MAPs become compartmentalized differently in each type of neurite? 3. Why does a neuron have a single axon but multiple dendrites?⁵

To help you, the researcher, to answer these questions (as well as many others regarding MT functions in the central nervous system!) for a number of years now we’ve been providing a reliable range of kits by Cytoskeleton Inc. Their highly useful reagents include the Signal-Seeker Enrichment kits for quantifying levels of endogenous PTMs such as acetylation, tyrosine phosphorylation, ubiquitination, and SUMOylation, as well as purified cytoskeletal proteins (e.g., actins, tubulins, kinesin and dynein motors) and functional assay kits to measure the activities of these same proteins.
