Monodispersed Magnetic Urea-Formaldehyde Microspheres (C09-0941-113)

This product is a brown suspension, dispersion solvent for the phosphate buffer solution (PBS). Monodisperse magnetic microspheres of urea-formaldehyde resin having a good monodisperse magnetic response. Suspension was long home to be a settlement, shaking, ultrasound can be re-dispersed magnetic microspheres. Monodisperse magnetic microspheres of urea-formaldehyde resin has a particle size distribution, the settling velocity consistent and superparamagnetic response characteristics of the magnetic field. Binding on a series of different chemical functional groups and having a specific antibody, protein and nucleic acid at the surface of the magnetic microspheres by chemical modification, can be applied to the purification of nucleic acids, cell selection, immune analysis, clinical diagnosis, and other fields, medicine, molecular an integral part of the separation and purification of biological research tool. [Precautions] Monodisperse magnetic microspheres of urea-formaldehyde resin dissolved in an organic solvent such as acetone, chloroform, tetrahydrofuran, and therefore can not be mixed with the reagent. (2) The operating temperature should not exceed 100 ℃, to avoid melting deformation or bonded into a group of microspheres. Before shaking scattered ultrasonic contribute to the dispersion of the magnetic microspheres. 4. Washed with PBS solution before use. [Specifications] 5 ml PBS suspension of the magnetic microspheres dispersed urea-formaldehyde resin solids content of 1% (w / v) [Solvent] PBS pH 7.40 Sodium azide 0.01% (preservative) Features: 1, high magnetic response to sexual the (saturated susceptibility> 13.7emu / g) 2, low coercivity. Specification: Matrix: UF,Surface group:-Epoxy,3-4um part. size,,10mg/ml in 1 %（w/v）PBS Buffer Related Documents: https://ald-pub-files.oss-cn-shanghai.aliyuncs.com/aladdinsci/pdp/sds/1/M120258-SCI_cd9c5bb84f8b71fd9dbf5cb1dfdeb5f6.pdf
