A Computational Screening protocol for Antifreeze/Ice-Structuring Proteins - http://www.natureprotocols.com/2006/08/17/afpredictor_a_computational_sc.php

Category: Bioinformatics

Using AFPredictor, it was demonstrated that ‘ordered surface carbons’ (OSCs) are a distinguishing feature of AFPs and, more specifically, their ice-binding surfaces. AFPredictor identified AFPs from within a large set of structures with greater than 99% specificity. Furthermore, it was used to identify a novel ice-binding protein by screening a library of homology modeled structures based on cDNA sequences obtained from cold-acclimated winter rye (Secale cereale). - [Read A Computational Screening protocol for Antifreeze/Ice-Structuring Proteins]

A Novel Fluorescent pH Probe for Expression in Plants - http://www.plantmethods.com/content/2/1/7

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

The pH is an important parameter controlling many metabolic and signalling pathways in living cells. Recombinant fluorescent pH indicators (pHluorins) have come into vogue for monitoring cellular pH. They are derived from the most popular Aequorea victoria GFP (Av-GFP). Here, we present a novel fluorescent pH reporter protein from the orange seapen Ptilosarcus gurneyi (Pt-GFP) and compare its properties with pHluorins for expression and use in plants. - [Read A Novel Fluorescent pH Probe for Expression in Plants]

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]

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.
