The coating on the SCHOTT NEXTERION® Slide P is a three-dimensional, hydrophilic polymer activated with N-Hydroxysuccinimide (NHS) esters to provide covalent immobilisation of amine groups. All NEXTERION® microarray slides are manufactured from a high quality, low-fluorescence glass coated with low-fluorescence coatings. However the non-specific binding of assay components, especially from serum samples, still remains an important contributor to the off feature background for many microarray applications. For most types of slide coatings the post-print processing protocol involves a method of adsorptive blocking to reduce non-specific binding; however these procedures are difficult to perform in a consistent manner.
The NEXTERION® Slide P coating has been engineered to exhibit an extremely low intrinsic non-specific background without the need for blocking. This was achieved by using a special polymer that is extremely resistant to non-specific binding. During in-house tests run by SCHOTT, NEXTERION® Slide P had the lowest background signal of any microarray slide coating ever tested. The polymer coating has a three-dimensional structure; with NHS-ester reactive groups attached to the hydrophilic polymer layer. The surface-exposed amino-groups on the antibodies react immediately and irreversibly with the NHS-ester groups forming covalent bonds. The polymer coating maintains the immobilised antibodies in a quasi-liquid environment that maintains their functionality and specificity. The polymer, combined with the end-point attachment, orients the immobilized bio-molecules away from the glass facilitating the interactions of the attached antibodies with the target antigens in the assay sample.
Product details
NEXTERION® Slide P is fabricated using a proprietary deposition process developed by SCHOTT to produce a uniform and reproducible polymer coating on one side of a high quality borosilicate glass slide. All slides are individually examined for physical defects and the absence of particle contamination before and after coating. The coating is applied in a tightly controlled, Class 100 clean room facility, resulting in coated slides with highly uniform surface properties and low auto-fluorescence.
Excellent spot morphology and signal-to-background ratios
NEXTERION® Slide P provides excellent spot morphologies and reproducible spot sizes over a wide range of probe concentrations.
