Protocol describes the practice of stripping immunoblots and reprobing to detect multiple proteins on the same blot is a good method to examine two antigens under identical conditions. - [Read Stripping Immunoblots for Reprobing or Storage Protocol]
Protocol describes the preparation of subtracted cDNA probes by hybridization to an mRNA driver, followed by purification of the single-stranded radiolabeled cDNA by hydroxyapatite chromatography. Before preparing the probe, it is a good idea to have filters (which contain the cDNA library to be screened) ready to hybridize. - [Read Synthesis of Radiolabeled, Subtracted cDNA Probes Using Oligo(dT) as a Primer 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.
