sperm Protocols

Category: Xenopus Protocols: Xenopus Egg Extracts Protocols

Protocol describes the preparation of nuclei from Xenopus sperm. These nuclei can be used for spindle assembly assays, microscopy, or DNA synthesis. - [Read Preparation of Xenopus Sperm Nuclei Protocol]

Category: Cell Biology and Cell Culture: In Vitro Reconstitution Protocols

This protocol describes an in vitro reaction to assay mitotic spindle assembly. The assay uses Cytostatic Factor extract made from Xenopus eggs, fluorescently-labelled tubulin, and prepared sperm nuclei. Spindle assembly is monitored by immunofluorescence microscopy. - [Read Protocol Spindle Assembly In Vitro]

Category: Drosophila Protocols: Drosophila Genetics Protocols

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]

Category: Xenopus Protocols: Xenopus Egg Extracts Protocols

Protocol for Xenopus sperm nuclei preparation. Sperm Nuclei can be made and stored as a stock for later use with Cytostatic Factor Extracts. - [Read Xenopus Sperm Nuclei Preparation Protocol]
