Protocol for in vitro mutagenesis using double-stranded DNA templates. Two oligonucleotides are used to prime DNA synthesis catalyzed by a high-fidelity thermostable polymerase on a denatured plasmid template. The two oligonucleotides both contain the desired mutation and occupy the same starting and ending positions on opposite strands of the plasmid DNA. - [Read In Vitro Mutagenesis Using Double-stranded DNA Templates: Selection of Mutants with DpnI]
The results of cytotoxicity tests in primary cultures of rat hepatocytes and in MDBK and McCoy cells can be used to predict the in vivo 4-wk maximum tolerated dose in rats and dogs. A correlation between in vitro cytotoxicity, as measured in this system, and LD50 values in rats and mice has also been established. - [Read In Vitro Prediction of the Maximum Tolerated Dose Protocol]

In Vitro Translated Xenopus Mos Kinase Assay Protocol. In response to progesterone, immature Xenopus oocytes mature to eggs that can be fertilized. The Mos protein kinase is essential for oocyte maturation, most likely due to its ability to activate the MAP kinase cascade. This MAP kinase cascade eventually leads to the activation of Cdc2/cyclin B and entry into M phase. In this protocol, tagged Mos kinase is translated in vitro, immunopurified, and used in a kinase assay.
