This protocol describes a battery of methods that includes analytical size-exclusion chromatography to study histone chaperone oligomerization and stability, pull-down assay to unravel histone chaperone-histone interactions, AUC to analyze the stoichiometry of the protein complexes, and histone chaperoning assay to functionally characterize a putative histone chaperone in vitro.

The zebrafish has recently been exploited as a model to validate potential radiation modifiers. The present protocol describes the detailed steps to use zebrafish embryos for radiation-based screening experiments and some observational approaches to evaluate the effect of different treatments and radiation.

This protocol describes a behavioral assay for recording sugar-elicited search behavior using Drosophila melanogaster. The assay can be utilized to study feeding and foraging-related behaviors, as well as the underlying neuronal mechanisms.

This protocol outlines a methodology for recapitulating Down syndrome (DS) impaired neurogenesis using DS human iPSCs. The protocol identified biphasic cell cycle defect as the cause of impaired neurogenesis in Down syndrome. It provides a robust platform for understanding cellular and molecular mechanisms underlying the abnormal neurogenesis associated with DS.
