Immunoprecopitation method, the protein from the cell or tissue homogenate is precipitated in an appropriate lysis buffer by means of an immune complex which includes the antigen (protein), primary antibody and Protein A-, G-, or L-agarose conjugate or a secondary antibody-agarose conjugate - [Read Protocol Immunoprecipitation]
Protocol describes the standard method to recover nucleic acids from aqueous solutions by precipitation of DNA with ethanol. Subnanogram amounts of DNA (and RNA) can be quantitatively precipitated with ethanol, collected by centrifugation, and redissolved within minutes. - [Read Standard Ethanol Precipitation of DNA in Microcentrifuge Tubes 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.
