背景(Background)

The Human PSMA-coupled Magnetic Beads is produced by coupling biotinylated human PSMA protein to streptavidin-conjugated magnetic beads. The pre-coupled beads are ready to use for capturing anti-PSMA antibody from your sample with high specificity. The uniform size and large surface-to-volume ratio of the beads ensure highly efficent immunocapture in a simple, fast and convenient workflow with high reproducibilty of data.

表达区间及表达系统(Source)

Human PSMA protein is expressed from human 293 cells (HEK293). It contains AA Lys 44 - Ala 750(Accession # Q04609-1 ).

应用说明(Application)

This product is intended for immunocapture, biopanning and flow cytometry. This product is produced non-sterile.

*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 -70°C. The shelf life is 1 year at -70 °C.

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.
