Ubiquitin-dependent molecular chaperone p97, also known as valosin-containing protein (VCP) or Cdc48, is an AAA ATPase involved in protein turnover and degradation. p97 converts its own ATPase hydrolysis into remodeling activity on a myriad of ubiquitinated substrates from different cellular locations and pathways. In this way, p97 mediates extraction of targeted protein from cellular compartme...

Silkworm (Bombyx mori) is a species of agricultural importance, as well as a model organism for Lepidoptera insects. Proteomic method has been widely used in silkworm research, and a robust mass spectrometry-compatible protein extraction method is urgently needed. In this study, we adapted phenol extraction method to extract silkworm midgut protein, and coupled this method with pH 5 8 gel strip...

soybean mosaic virus (smv) which belongs to the virus family potyviridae, causes a disease in soybean that is present in soybean-growing areas of the world, and is widely distributed in northern iran. detection of smv is very important for disease management. in the present study several serological and molecular (nucleic acid- based) methods of rapid virus detection were compared. serological ...

We compared results obtained by (a) chemical (spectrophotometric) and competitive protein-binding assays for serum corticosteroids, and (b) competitive protein-binding and radioimmunoassay, with and without CCI-4 extraction, for serum cortisol. The two corticosteroid methods gave identical results. Radioimmunoassay with and without a CCI-4 extraction step gave identical results for cortisol. Co...

The purpose of this study is to investigate the performance and efficiency of Moringa seeds from different sources on turbidity. A protein analysis test was done for each source; then two different methods of extraction were compared to examine the coagulation activity for the Moringa's active ingredient. The results of sodium chloride (NaCI) extraction in comparison to distilled water extracti...

Many different extraction and analysis methods exist to determine the protein fraction of microbial cells. For metabolic engineering purposes it is important to have precise and accurate measurements. Therefore six different protein extraction protocols and seven protein quantification methods were tested and compared. Comparison was based on the reliability of the methods and boxplots of the n...
