Absorbance Assay 205 nm - http://www.ruf.rice.edu/~bioslabs/methods/protein/abs205.html

Category: Protein Protocols: Protein Quantitation Concentration Protocols

Absorbance assay at 280 nm. This method is just as convenient as for absorbance at 280 nm. It may be preferred if there is excessive contamination by nucleic acids, since nucleic acids absorb very little radiation at 205 nm. Setting the wavelength is a bit tricky since 205 nm is right on the shoulder of the protein peak. - [Read Absorbance Assay 205 nm]

Absorbance Assay 280 nm - http://www.ruf.rice.edu/~bioslabs/methods/protein/abs280.html

Category: Protein Protocols: Protein Quantitation Concentration Protocols

Absorbance assays are fast and convenient, since no additional reagents or incubations are required. No protein standard need be prepared. The assay does not consume the protein. The relationship of absorbance to protein concentration is linear. Because different proteins and nucleic acids have widely varying absorption characteristics there may be considerable error, especially for unknowns or protein mixtures. - [Read Absorbance Assay 280 nm]

Traditional animal models to quantify the degree of blood vessel formation are being replaced by cell culture assays that are easier to set up, statistically reliable and can be automated in a drug screening laboratory. These assays rely on the endothelial cells’ ability to form distinct blood-vessel-like tubules in an extracellular matrix where they can subsequently be visualized by fluorescence microscopy. - [Read An Image-Based Assay of Endothelial Cell Tube Formation as a Model of Angiogenesis]

Analysis Of DNA Fragmentation Using The JAM Assay (Subscription Required) - http://www.cshprotocols.org/cgi/content/extract/2006/1/pdb.prot4432

Category: Cell Biology and Cell Culture: Apoptosis Protocols: Apoptosis Analysis

Analysis of DNA Fragmentation Using the JAM Assay. By Shailaja Kasibhatla et al., The JAM assay is based on labeling nuclear DNA of cycling cells with [3H]thymidine and harvesting samples on glass fiber filters. Apoptosis will generate DNA fragments small enough to pass through the glass fiber filter, resulting in decreased radioactivity of the particular sample. Cell-mediated cytotoxicity or cell killing mediated by cytotoxic T lymphocytes (CTL) can also be measured by this technique. - [Read Analysis Of DNA Fragmentation Using The JAM Assay (Subscription Required)]

Tubulin Polymerization Protocol using GTP and GMPCPP

Tubulin is polymerized into microtubules by incubating tubulin at 37°C with GTP. A nucleation seed is added when the purpose is to assay microtubule elongation. Tubulin can also be polymerized for the purposes of recycling the tubulin or labeling the microtubules with fluorescently labeled tubulin. Based on the protocol by Timothy Mitchison of Harvard University.

In Vitro Translated Xenopus Mos Kinase Assay 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.
