Glycan arrays and glycomics

Glycan arrays and glycomics

Glycan arrays offer significant advantages for glycomics research - mainly, in that a broad range of multivalent glycans can be immobilised on a solid surface and interrogated simultaneously. High-density glycan arrays can be printed using Arrayjet microarray spotters, enabling the analysis of up to 75,000 binding events on a single microarray slide.

Researchers at the University of Copenhagen use a Marathon Argus non-contact microarray spotter to print their glycan arrays.

"The production of microarrays of complex and diverse carbohydrates presents particular unique challenges. The Arrayjet microarray spotter works very well for this purpose and in our experience, is superior to pin based printers. We have found that the Arrayjet printer is very fast, accurate and most important, able to handle polysaccharides and oligosaccharides with widely different chemical and physical properties. What is also impressive is that we are able to print extracted material directly without clean up, despite the fact that some extraction solvents are very harsh, for example, 4 M sodium hydroxide.''
