RECENT CITATIONS: RECOMBINANT PROTEINS: NEURONAL OUTGROWTH, SURVIVAL, AND GUIDANCE

R&D Systems offers a wide selection of active recombinant proteins to facilitate study of the mechanisms that regulate the growth and guidance of axons. These include classical axon guidance cues such as Netrins, Semaphorins, Ephrins, cell adhesion mole­cules, and their corresponding receptors. Also available are a range of tools to study regulators of axon outgrowth and survival including mem­bers of the neurotrophin family, their receptors, co-receptors, and myelin-associated proteins. Several recent studies have utilized R&D Systems products to assess the roles of these factors during development, regeneration, and neurode­generative disease.
