NEXTERION® Slide E

NNEXTERION® Slide E is the market leading epoxy coated slide from SCHOTT. The slides are manufactured from high quality borosilicate glass that has an ultra flat surface and low inherent fluorescence. The glass is coated with a multi-purpose epoxysilane layer that will covalently bind most types of bio-molecules including amino- and non-modified DNA, RNA, and proteins. The defect-free surface features a uniform epoxysilane layer that provides 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.

Immobilization chemistry

The diagram shows a schematic representation of an amino-modified DNA molecule coupling to NEXTERION® Slide E. Amino-modified nucleic acids bind via the terminal amino group, as well as via exocyclic amino groups of the bases, and hydroxyl groups of the sugar-phosphate backbone. Unmodified nucleic acids will bind to an epoxysilane surface with almost the same efficiency via the exocyclic amino groups of the bases, and hydroxyl groups of the backbone. Other bio-molecules such as proteins bind via their exposed amine-, thiol- and hydroxyl-groups. The reaction with the epoxy group is rapid and irreversible and no additional baking or UV cross-linking steps are required. Any unreacted epoxy group may be chemically deactivated after printing to significantly reduce nonspecific binding of the target molecules to the slide surface. Molecular spacers between the glass slide and the epoxy groups facilitate interactions between the printed bio-molecules and their binding partners in solution.

Product details  Highly reproducible coating

 
NEXTERION® Slide E is produced using an innovative proprietary process developed by SCHOTT to produce a uniform and reproducible epoxysilane coating on both sides of a high quality borosilicate glass slide. All slides are individually examined for physical defects and the presence of particles before and after coating. The epoxysilane surface is applied in tightly controlled, class 100 clean room facility, resulting in coated slides with highly uniform surface properties and low auto-fluorescence.
 
Fully optimized surface
NEXTERION® Slide E provides excellent spot morphologies and reproducible spot sizes with a variety of commonly used spotting buffers. The surface chemistry is robust and stable, and remains active even during very long print runs. The density of the epoxy groups in the coating is constant over the entire surface of the slides, and has been optimized to provide uniform spot size and shape and the optimal binding capacity. Another important parameter, surface hydrophobicity, is also tightly controlled to optimize the performance of the slides with both contact and non-contact printers.
 
Packaging and storage
NEXTERION® Slide E are packaged in chemically stable plastic boxes and sealed under an inert atmosphere. The slides are ready-to-use from the box, and are stable for 12 months in the sealed packaging when stored at room temperature.
 
Format
The slides are available in packs of 25 slides with optional code 128 barcodes enabling automated sample tracking. The identical epoxysilane coating is also available in 16-well slide, 48-well slide and 96-well microplate multi-well formats.
