Preparative Gel Electrophoresis Purification of Marine Polysaccharides

Preparative Gel Electrophoresis Purification of Marine Polysaccharides

Achieve Precision Polysaccharide Separation with CD BioGlyco's Gel Electrophoresis Expertise

Preparative gel electrophoresis is a technique using an electric field to separate Marine Polysaccharides based on both size and charge. The method involves passing a mixture of polysaccharides through a polyacrylamide or agarose gel matrix, wherein smaller molecules migrate faster than larger molecules under the influence of the electric field. The isolated polysaccharides are then extracted from specific gel bands for further analysis or use.

This method provides excellent resolution and allows for the separation of polysaccharides with small differences in size or charge. It is suitable for the separation of a wide range of marine polysaccharides such as glycosaminoglycans (GAGs), fucoidan, alginate, carrageenan, and so on. Based on our Comprehensive Technology for Marine Polysaccharides, CD BioGlyco provides custom, highly flexible marine sugar separation and purification services to our clients.

Here are some of the key steps that need to be taken care of during the preparative gel electrophoresis purification technique, and we can make these steps customized according to the client's requirements.

  • Gel preparation: Choose the appropriate gel type (polyacrylamide or agarose) according to the size and nature of the polysaccharide.
  • Electrophoresis: The electrophoresis instrument is set to the appropriate voltage and current settings according to the gel type and the desired separation resolution.
  • Detection and extraction: After electrophoresis, the gel is stained using a suitable stain (e.g. Alcian blue for glycosaminoglycans) to visualize polysaccharide bands.
  • Purification and concentration: The recovered polysaccharide solution is dialyzed to remove small molecules and impurities. The purified polysaccharide solution is concentrated using methods such as lyophilization or rotary evaporation.
  • Quality control: The purified polysaccharide is analyzed using high-performance liquid chromatography (HPLC), mass spectrometry (MS), or nuclear magnetic resonance (NMR) to determine its purity, molecular weight, and structural characteristics.

Journal: Researchsquare

Published: 2021

Results: This paper explores a MP-PAGE technique for the purification of biological and nanomaterials. The technique demonstrates high efficiency in recovering purified DNA from DNA mixtures and high purity in purifying proteins from crude cell extracts, and can be successfully used to separate nanoparticles of different sizes from GQD mixtures. This method not only avoids complex gel preparation and disassembly steps, but also does not require expensive specialized equipment, making it potentially widely applicable in most bioanalytical laboratories.

Applications

  • Gel electrophoresis can be used to achieve efficient separation, especially for the complex structure and diverse molecular weight distribution of marine polysaccharides.
  • Polysaccharides purified by gel electrophoresis can be used to study their biological activity, structural characteristics, and their potential applications.
  • Gel electrophoresis technology can make sure that marine polysaccharides maintain their bioactivity and functional properties during the purification process.

Advantages

  • Gel electrophoresis can realize high-resolution separation of polysaccharides of different molecular weights and structures, and It is especially suitable for polysaccharide samples with complex molecular weight distribution.
  • Due to its gentle processing condition, gel electrophoresis can protect the biological activity and structural integrity of polysaccharides from degradation due to high temperatures or chemical reagents.
  • Gel electrophoresis applies to many types of polysaccharides, including polysaccharides of marine origin and other natural polysaccharides.
