Self-propagating abnormal proteins, prions, have been identified in yeast; asparagine/glutamine-rich 'prion domains' within these proteins can inactivate the linked functional domains; new prion domains and reporters have been used to make 'synthetic prions', leading to discoveries of new natural prions.
In Utero Electroporation is a powerful tool for testing the role of genes in neuronal migration, but this technique suffers from high degrees of variability due to multiple factors. Therefore, we developed Double UP, a novel approach that combines LoxP-flanked reporters and limiting Cre dosages to generate internal controls. This technique allows for more rigorous quantification of migration, while decreasing the number of animals, reagents and time to complete experiments.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
