Kit for Rapid Enrichment of SARS Virus - http://www.gentaur.com/sars_isolation.htm

Category: Viral Culture and Isolation Protocols: Viral Isolation Protocols

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]

Metabolic Labeling & Immunoprecipitation Protocols - http://www.cbrinstitute.org/labs/springer/protocols/jun_35Slabeling_IP.html

Category: Immunology: Immunoprecipitation Protocols: Immunoprecipitation of Radiolabeled Cells Protocols

Cells incorporate 35S-methionine or cysteine during the protein synthesis. Thus it is essential to use Met,Cys-free medium and dialyzed FCS during the labeling. Short period of incubation with 35S-methionine or cysteine will result in radiolabeling (pulse), and additional incubation with excess concentration of unlabeled Met+Cys (chase) is needed for complex glycoproteins like integrins to get expressed as a maturated form. - [Read Metabolic Labeling & Immunoprecipitation Protocols]

The Isolation and Culture of Rat Hepatic Cells Protocol - http://embryo.ib.amwaw.edu.pl/invittox/prot/7.htm

Category: Mouse Protocols: Mouse Cell Culture Protocols

The liver of a rat is cannulated and perfused in situ with buffer, following which it is excised and perfused in a closed system with a collagenase solution. After a period of time the liver begins to break up, at which point it is transferred to a measuring cylinder and culture medium is added. It is then gently agitated to cause the release of cells which are subsequently filtered and allowed to settle out. The parenchymal and non-parenchymal cells form two distinct layers which can be separat - [Read The Isolation and Culture of Rat Hepatic Cells Protocol]

Category: Epigenetics and Methylation Protocols: 5-Aza-dC Treatment AZA Procedure

"Cells were seeded at a density of 1X106 cells/100-mm dish with 10% FBS and allowed to attach over a 24-h period. 5-Aza-dC (Sigma) was then added to a final concentration of 0.2â€“1 M, and the cells were allowed to grow for 5 days. The medium with or w - [Read Treatment of Cells with 5-aza-dC. protocol PDF]

Absorption Spectroscopy and Quantification of Filamentous Phage Protocol

Unlike spherical phage, such as T4 and λ, which have roughly equal weight ratios of protein to DNA, filamentous phage have about six times more protein than DNA; the protein therefore contributes substantially to the absorption spectrum.
