PolyAn is the European distributor of the nitrocellulose based microarray product families developed by Grace Bio-Labs.

ONCYTE® porous nitrocellulose (PNC) slides are the optimal high binding protein microarray substrate technology available. Invented by Grace Bio-Labs scientists, the three dimensional microporous film cast on a variety of solid surfaces (vis. glass, plastic, gold, tantalum) is comprised of a nitrocellulose polymer and proprietary chemistry that retains stable protein quaternary conformations providing ideal microarray substrate for a variety of applications.  ONCYTE® film provides an excellent surface when performing reverse phase protein arrays (RPPA), antibody arrays, antigen or peptide arrays whether using colorimetric, fluorescent or near infra-red detection systems.

The ONCYTE™ and SuperNOVA™ slides are available as single film or in various multi-pad formats. The film is compatible with fluorescent, chemoluminescent, radiographic, and colorimetric detection systems. It is manufactured to the highest standards, providing excellent reliability and reproducibility.

The PATH® Protein Microarray Slide is coated with an ultra-thin nitrocellulose film for the noncovalent, yet irreversible, binding of printed antibodies to the slide surface while maintaining antigen binding capability. PATH® slides provide maximum reliability, sensitivity, and reproducibility of multiplex protein microarray immunoassays, in addition to reducing background fluorescence and maximizing signal-to-noise ratios.
