背景（Background）
The Human B7-H3-coupled Magnetic Beads is produced by coupling biotinylated human B7-H3 protein to streptavidin-conjugated magnetic beads. The pre-coupled beads are ready to use for capturing anti-B7-H3 antibody from your sample with high specificity.
表达区间及表达系统（Source）
Human B7-H3 Protein is expressed from human 293 cells (HEK293). It contains AA Gly 27 - Thr 461(Accession # Q5ZPR3-1).
应用说明（Application）
This product is intended for immunocapture, biopanning and flow cytometry. This product is produced non-sterile.
重构方法（Reconstitution）
See Certificate of Analysis (CoA) for detailed instruction.
存储（Storage）
Upon receipt, please store the beads at -20°C for 1 year in lyophilized state.
Please avoid more than 3 freeze-thaw cycles once reconstitution, immediate use after reconstitution is highly recommended.
原理（Assay Principles）
Antibody Purification: 1. Reconstitute the beads with ultrapure water to 1 mg/mL, and wash the beads for three times. 2. Dilute the biotinalyted protein or antibodies with Assay Buffer and add to the beads. Incubate for 60 minutes at room temperature in a rotary mixer. 3. Wash the beads for four times, and add Assay Buffer to the beads. The beads are ready to use for the next experiment.
The magnetic beads technology makes use of the easy and efficient collection of beads in magnetic field to facilitate antibody purification in a simple workflow of “bind-wash-elute”. In contrast to common separation techniques, this method does not require columns or centrifugation, and is therefore ideal in high-throughput applications.
