Protocol describes rapid, small-scale yeast RNA isolation. It is based on the work of Schmitt et al. (1990). Note that all containers should be washed in Rnase Away (Invitrogen) or dry baked for 24 hours at 160°C. - [Read Yeast RNA Isolation: Small-Scale 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.
