Pulse-Chase Assay for Measuring Protein Stability in Yeast Protocol - http://www.cshprotocols.org/cgi/content/abstract/2007/1/pdb.prot4641

Category: Yeast Protocols: Yeast Protein Protocols

This assay directly measures the stability of a specific protein in yeast. Following pulse-labeling of yeast cells, the target protein is recovered by denaturing immunoprecipitation. - [Read Pulse-Chase Assay for Measuring Protein Stability in Yeast Protocol]

Quantitative GUS Activity Assay of Plant Extracts - http://www.cshprotocols.org/cgi/content/abstract/2007/3/pdb.prot4690

Category: Plant Biology Protocols: Plant Proteins, Peptides and Antigens

Using excitation at 365 nm and measuring emission at 455 nm, the amount of 4-MU produced can be quantified. Under these conditions, background fluorescence from the substrate is negligible, especially if the appropriate filter is selected. - [Read Quantitative GUS Activity Assay of Plant Extracts]

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]

Titering" a phage means measuring the concentration of phage in a given solution. Titering Procedure. Rob Philip's Group. - [Read Titering & Propagation of Phage]

Yeast Growth Rate Cytotoxicity Test - http://embryo.ib.amwaw.edu.pl/invittox/prot/33.htm

Category: Pharmacology and Toxicology Protocols: Cytotoxicity Protocols: Microorganism Cytotoxicity Assays Protocols

The proliferation rate of the yeast, Saccharomyces cerevisiae, may be regarded as an overall indicator of the physiological status of the cell. Therefore, the effect of various toxic substances on different cell functions will be reflected by changes in the rate of proliferation. It is possible to determine the toxicity of a test substance simply by measuring cell density. - [Read Yeast Growth Rate Cytotoxicity Test]

Yeast Plasma Membrane H+ -ATPASE Toxcity Test Protocol - http://embryo.ib.amwaw.edu.pl/invittox/prot/34.htm

Category: Yeast Protocols

Plasma membranes are isolated from the yeast Saccharomyces cerevisiae. The cell wall is initially digested by helicase, followed by hypoosmotic lysis and homogenization. Membranes are prepared by subsequent differential centrifugation. The activity of the H+-ATPase is then determined by measuring the amount of inorganic phosphate released from ATP. - [Read Yeast Plasma Membrane H+ -ATPASE Toxcity Test Protocol]

Genomic DNA Labeling of Microarrays Protocol

DNA microarrays are an ordered arrangement of DNA molecules complementary to genes of interest that are "spotted" by robotic equipment onto a glass slide substrate. The expression of genes in cells can be monitored with microarrays by preparing cDNA from the mRNA of cells of interest and measuring the hybridization to the microarray. This protocol describes the labeling of genomic DNA for use as a probe for hybridization to the cDNA spotted on the array.

Microarray Protocol Preparation of Fluorescent DNA Probes from Human mRNA

This Microarray Protocol Preparation of Fluorescent DNA Probes from Human mRNA protocol describes the production of probes labeled with the fluorescent dyes, Cy3 and Cy5, following the synthesis of cDNA from human mRNA and the hybridization of the probes to DNA microarrays.

Acid Guanidinium Thiocyanate RNA Isolation Phenol Chloroform Extraction

A single step RNA isolation protocol using Phenol Chloroform Extraction and Acid Guanidinium Thiocyanate. This RNA isolation method uses the fact that guanidinium thiocyanate can simultaneously lyse the cells and inactive cellular RNAses during the initial RNA isolation step allow a single step in the method.
