Cytostatic factor extract (CSF) preparation for spindle assembly protocol. Protocol includes tips such as: The quality of the eggs is essential for good CSF extracts. Always sacrifice quantity for quality when trying to make functional extracts. - [Read Cytostatic Factor (CSF) Extract Preparation for Spindle Assembly Protocol]

Category: Xenopus Protocols: Xenopus Egg Extracts Protocols

Protocol for cytostatic factor extract preparation for spindle assembly. The quality of the eggs is essential for good CSF extracts. Always sacrifice quantity for quality when trying to make functional extracts. Discard any batches of eggs that have "puff balls" or activated eggs that constitute more than 10% of the eggs. Use laid eggs and collect eggs at about 16 to 17 hours after priming with Progesterone (found in Pregnant Mare Serum Gonadotropin (PMSG)). - [Read Cytostatic Factor (CSF) Extract Preparation for Xenopus Spindle Assembly Protocol]

Flow cytometry is used to analyze the quantity of DNA in cells. Since the DNA content of cells varies through the cell cycle, this information can provide an indication of cell cycle progression. This protocol uses SYTOX Green staining. - [Read Preparation of Yeast Cells for Flow Cytometry Protocol]
