Product Description | White solid powder, It can be uniformly dispersed in an organic solvent and water and to become a white suspension. Uniform Silica Microspheres with uniform particle size distribution , high purity , and can be used in microscopy , cell measurements , biomedical , filtration and flow detection principle research and other fields. Uniform Silica Microspheres can be bonded to the surface of -NH2,-COOH, albumin, protein A, an epoxy group , NTA, EDTA, streptavidin -biotin and the like groups , fluorescent groups can also be connected to form a functional of fluorescent microspheres for coupling DNA, oligonucleotide , oligo peptides , proteins , lectins, antibodies and the like . [Precautions ] 1 Uniform Silica Microspheres can be long-term storage in ethanol , methanol , tetrahydrofuran and other organic solvents , do not long-term storage of bonded phase silica microspheres in the water , it will cause the loss of bonded phase . 2 Uniform Silica Microspheres easily fluorinated solvents and other corrosive hydrofluoric acid , under strong alkaline conditions can also cause silica hydrolysis using a pH range of 2-10 at room temperature and atmospheric pressure. 3 ultrasonic bath 10 min prior to use to help its dispersed. 2.5% (w / v) in ethanol |
