This chemotaxis assay protocol is based on the premise of creating a gradient of the chemotactic agent and allowing cells to migrate through a membrane towards the chemotactic agent. A chemotaxis assay can determine whether your protein or small molecule of interest has chemotactic activity on a specific cell type. Chemotaxis is then the ability of a protein to direct the migration of a specific cell. - [Read Chemotaxis Assay Protocol]

Protocol describes the general procedure for creating mutations in the DNA of Drosophila by exposure to X-rays. Irradiation of cells with X-rays creates double strand breaks (DSBs) in DNA. Mutations introduced in the DNA of germ line cells (sperm) are propagated by mating the exposed males to virgin females. The progeny of this cross can be mated to each other so that a percentage of the subsequent offspring will have two copies of the same mutant allele. - [Read X-Ray Mutagenesis of Drosophila Protocol]
