Diagnostic Membranes and Arrays
Rapid diagnostic tests are sustaining a rapid growth as they become a major segment in the Point of Care IVD (In Vitro Diagnostic) world market. Two formats using microporous membranes are the most common in IVD devices: The Lateral flow strip and the immunoblot strip. Though, due to its simplicity, the lateral flow format is from far the most popular. Sartorius has developed special nitrocellulose membranes which are today a reference for consistency in IVD strips or new protein arrays.
Protein microarrays (or biochips) are indispensable tools for many proteomic applications and new multi-parameter IVD tests. The UniSart® 3D Nitro slides have been designed to be the best substrate for protein array applications, e.g., direct protein arrays (forward capture protein or antibody assays) and reverse phase protein microarrays (or lysate arrays). The multiplicity of protein spots, displayed on the slide surface, permit various biomolecular interactions to be viewed simultaneously.
