Microarray slides

XanTec bioanalytics has developed a selection of hydrogel coated slides for both DNA and protein microarrays. DNA microarrays require low background signal, and minimal intra- and slide-to-slide deviation is crucial. Spotting is usually a straightforward process, as DNA is relatively robust. On the other hand, protein microarrays are more delicate. Proteins can't be immobilized on the same types of materials, for they are extremely sensitive to the physical and chemical properties of any particular substrate. In addition, protein interaction surfaces must be bioinert and have to provide a much higher immobilization capacity than that required in DNA microarrays. Therefore, our microarray slide portfolio is specialized and divided into DNA and protein sections.
