Because sequencing reactions catalyzed by thermostable DNA polymerasessuch as Taq are carried out at elevated temperatures, problemscaused by mismatched annealing of primers or templates richin secondary structure are greatly alleviated. - [Read Dideoxy-mediated Sequencing of DNA Using Taq DNA Polymerase Protocol]
During incubation period and the course of disease, SARS virus replicates and releases from cells. The level of virus varies greatly from sample to sample. At early stage of incubation period or during the late convalescent phase, the concentration of virus is very low in all kinds of samples. Virus is also detected at extremely low concentrations in plasma during... - [Read Kit for Rapid Enrichment of SARS Virus]
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.
