Protein microarray technology provides a robust way to study protein function in a rapid, economical, and system-wide fashion. Protein microarrays are playing an increasingly important role in proteomic research, as well as moving into the arenas of drug discovery and clinical diagnostics. For many of these protein array applications, the slide surface of choice is nitr ocellulose. The unique properties of cellulose nitrate polymers, such as high affinity, and high capacity for protein binding, together with their micro-porous structure makes this material an ideal substrate for protein array applications.

To meet the needs of this rapidly expanding market, SCHOTT has joined forces with Sartorius Stedim Biotech GmbH, to develop a range of innovative nitrocellulose-coated microarray slides. Sartorius Stedim Biotech GmbH is the perfect co-development partner for this product line, as they have been manufacturing cellulose nitrate membranes for nearly eighty years. Nitrocellulose formulations from Sartorius Stedim Biotech GmbH have proven their reliability over the years, in Western Blots, and in diagnostic membranes, such as pregnancy tests. The diagnostic membrane production expertise of Sartorius Stedim Biotech GmbH has been combined with SCHOTT’s microarray slide production know-how to produce protein microarray slides of superior quality, with high reproducibility.
