Trichloroacetic Acid/Acetone Precipitation Method to Optimize Canine Synovial Fluid for One and Two-Dimensional Gel Electrophoresis Studies

Two-dimensional Gel Electrophoresis

Two–Dimensional Gel Electrophoresis of Ceolomic Fluid of Eisenia foetida Earthworm

Earthworms possess antioxidant, antibacterial, antitumor, and hemolytic properties. To recognize the molecules responsible for various biological activities of earthworm’s coelomic fluid, a detailed knowledge about its protein contents is required. The aim of this study was to characterize the proteins present within the coelomic fluid of Eisenia foetida earthworm. Polyacrylamide-gel-elec...

Two-dimensional gel electrophoresis of cerebrospinal fluid proteins.

Two-dimensional electrophoresis, with isoelectric focusing in the first dimension and sodium dodecyl sulfate/polyacrylamide gel electrophoresis in the second, has been adapted for the high-resolution analysis of cerebrospinal fluid proteins. Proteins were detected with a new, highly sensitive silver stain that made visible more than 300 polypeptides from 60 microL of spinal fluid, in highly rep...

An Optimized Trichloroacetic Acid/Acetone Precipitation Method for Two-Dimensional Gel Electrophoresis Analysis of Qinchuan Cattle Longissimus Dorsi Muscle Containing High Proportion of Marbling

Longissimus dorsi muscle (LD) proteomics provides a novel opportunity to reveal the molecular mechanism behind intramuscular fat deposition. Unfortunately, the vast amounts of lipids and nucleic acids in this tissue hampered LD proteomics analysis. Trichloroacetic acid (TCA)/acetone precipitation is a widely used method to remove contaminants from protein samples. However, the high speed centri...

Separation of low molecular weight serum proteins using acetonitrile precipitation assessed by one dimensional gel electrophoresis

In human serum, low molecular weight (LMW) proteins play an important role in major biological processes which were masked by high molecular weight (HMW) proteins. Separations and identification of LMW proteins of interest from serum is very intricate task. The objective of the present study was to develop in-house acetonitrile (ACN) precipitation method for separation of LMW proteins from high...
