Products | BioPlusTM TEM Grids

BioPlus Grids are hydrophilic TEM grids with positive surface charge that provide simple, reproducible and high quality TEM sample preparation for biological molecules. The positive surface charge of BioPlus Grids, derived from primary amine-groups tethered to the grid surface, promotes non-specific electrostatic binding to a wide range of biological molecules including proteins, antibodies, and virus particles through NanoPlus negatively-charged functional groups including carboxylates, phosphates, and sulfates on the surface of the molecules.

Using simple preparation protocols, BioPlus TEM grids save valuable time and money by improving sample dispersion across the grids and by eliminating sample preparation-induced artifacts including aggregation and drying effects. TEM samples prepared with BioPlus TEM Grids show a uniform distribution of biomolecules with random orientation across the entire grid surface that simplifies both imaging and analysis of the sample.

BioPlus grids can also be used in a wide variety of biological assays including on-grid affinity purification, immunoassays, and targeting assays to improve the quality of the samples and resulting data. BioPlus grids are used in our LinkedON BioKits to enable immobilization of proteins to the grid surface through direct conjugation. For more information on affinity purification, immunoassays, and single particle analysis, please see our applications.

BioPlus Grids are now available with three different membranes types including our original SiO2 membranes and frames (no membranes), our 15 nm Si3N4 membranes and, most recently, our C-SMART carbon membranes that are setting a new standard for direct (unstained) imaging using cryoEM, electron tomography, and low voltage EM.
