Human CTLA-4 coupled Magnetic Beads
背景（Background）
The Human CTLA-4 coupled Magnetic Beads is produced by coupling biotinylated human CTLA-4 protein to streptavidin-conjugated magnetic beads. The pre-coupled beads are ready to use for capturing anti-CTLA-4 antibody from your sample with high specificity.
表达区间及表达系统（Source）
Human CTLA-4 Protein is expressed from human 293 cells (HEK293). It contains AA Ala 37 - Phe 162(Accession # Q6GR94-1).
应用说明（Application）
This product is intended for immunocapture, biopanning and flow cytometry. This is a non-sterile product.
The Isotype control (Cat. No. SMB-B01) is sold separately.
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. Resuspend the lyophilized beads by adding the buffer of choice.
2. Add analyte to the suspension, mix and incubate to enable specific binding of the beads and the target protein.
3. Magnetize beads, remove supernatant, and wash unbound protein fractions to capture target protein-bound beads.
4. Wash, magnetize the beads and collect purified target protein for use in downstream applications.
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.
