Protocol that investigates macrophage activation using a more homogeneous population of cells, macrophages derived from immature progenitor cells in bone marrow can be studied. A second protocol describes the isolation of bone marrow-derived progenitor cells and propagation of these immature macrophages by CSFs or IL-3. - [Read Isolation of Murine Macrophages 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.
