Microarray Glass Slides

PolyAn is proud to offer one of the broadest product portfolios of microarray substrates on the market. Our products include plastic and glass slides as well as functionalized 96-well plates for DNA-, peptide-, glycan- or protein microarrays. Applications range from low density microarrays for diagnostic tests to ultra-high density arrays for pharma screening

2D-functionalized Glass Slides

For cost-sensitive applications PolyAn has developed a range of 2D (2-dimensional)-reactive glass slides that are manufactured from high quality glass with an ultra-flat surface and low inherent fluorescence. The glass is coated with a thin silane layer that will covalently bind most types of bio-molecules. The defect-free surface features uniform silane layers that provide a high covalent coupling efficiency together with a very low background. The slides are easy to use, and are fully compatible with all commercially available arraying and scanning instruments

1) 2D-Azid functionalised glass slides for covalent coupling of Alkyne-or DBCO modified biochemical species via click-chemistry

2) 2D-PDITC (1,4-phenylenediiso-thiocyanate) activated amino groups react immediately with the NH2- terminus of biochemical species to form a covalent bond with the surface (420 kJ/mol)

Technical specifications

Dimensions: The slides are produced with standard dimensions of 25 x 75 x 1 mm. Additionally, we offer customized slides and alternative glass formats with surface modifications tailored to your specific application. Please also have a look at our ProPlate, HybriWell and SecureSeal products that facilitate handling of slides

Packaging: The slides are packaged in inert atmospheric boxes, with a capacity of 25 or 5 slides per box

Storage: PolyAn’s slides are characterised by a long shelf-life when stored dry, at 4-8°C and protected from sunlight. All slides are packaged in boxes under Argon atmosphere to avoid contamination with particles. The Argon atmosphere also minimises degradation of the reactive surface through contact with air or humidity

3D-functionalized Glass Slides

PolyAn’s 3D-functionalised microarray Slides are functionalized with a three-dimensional (3D)-surface chemistry comprised of a long-chain polymer containing a defined number of reactive groups. This polymer is covalently linked to the surface of the slide

1) 3D-NHS functionalized slides are used for covalent immobilization of biomolecules. The NHS-ester react immediately with the NH2- terminus of biochemical species to form a covalent bond with the surface

2) 3D-NHS functionalized slides are used for covalent immobilization of biomolecules. The NHS-ester react immediately with the NH2- terminus of biochemical species to form a covalent bond with the surface

3) Poly-L-Lysin surfaces are well suited for coupling of biochemical species. Especially, when the storage buffer contains glycerol Poly-L-Lysin surfaces are an interesting alternative to reactive matrices

4) 3D-PDITC (1,4-phenylenediiso-thiocyanate) activated amino groups react immediately with the NH2- terminus of biochemical species to form a covalent bond with the surface (420 kJ/mol)

5) 3D-Maleimide-surfaces for „click chemistry“ for oriented covalent coupling (immobilization) of thiolated biochemical species
