Consumables for Microarrays

PolyAn is proud to offer one of the broadest product portfolios of microarray consumables on the market. Our products include:

for DNA-, peptide-, aptamere, carbohydrate (glycans), RPPA or protein microarrays. Applications range from low density microarrays for diagnostic tests to ultra-high density arrays for pharma screening.

PolyAn is able to equip almost any substrate with our reactive matrices and antifouling surfaces. As part of our Molecular Surface Engineering services, we offer functionalized consumable and substrate materials for OEM applications, which are tailored to specified customer requirements.

In order to facilitate handling of slides PolyAn also offers a wide range of accessories like the SecureSeal Hybridization Chambers and the ProPlate multi-well chambers. PolyAn is also the European distributor of Grace Bio-Labs’ Nitrocellulose Film slides.

3D-Surfaces made by Molecular Surface Engineering

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.

Our MSE-technology gently binds the functional layer onto the surface without damaging the base substrate. The morphology of the functional surface and thus the number of the reactive groups can be fine-tuned within a narrow range. This yields a number of advantages:

Low fluorescence background Covalent binding of functional layer on the substrate without changing the initial autofluorescence.
Low unspecific binding Combination of reactive functional groups with PolyAn antifouling matrix.
Topography Tuneable surface
hydrophilicity / hydrophobicity (contact angle).
Uniform spot morphology Narrow variation of surface properties and homogeneous distribution of reactive groups.
Optimal density and high accessibility of reactive groups Morphology and thickness of functional layer tailored to the desired application.
