Upon receipt, please store the beads at -20℃ for 1 year in lyophilized state.
Please avoid more than 3 freeze-thaw cycles. Immediate use after reconstitution is highly recommended.
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.
Immobilized 61.5 μg S2 protein to 1 mg Beads can bind the Anti-SARS-CoV-2 S2 Antibody with an EC50 of 0.4837 μg/mL (QC tested).
ACROBiosystems has developed an exclusive immune checkpoint protein collection， The consistency and excellent performance of our proteins are confirmed by a variety of assays.
ACROBiosystems has developed a series of homogeneous CD3 proteins with good bioactivity. They are verified as 1:1 heterodimers by nonreductive electrophoresis and MALS as well.
ACROBiosystems has developed a series of products with different species and tags for a variety of hot targets. It is suitable for immune, antibody screening, SPR, cell activity detection and other experiments, and all SPR&BLI protocols are available for free.
We also supply difficult-to-express proteins such as BCMA, CD19, ROR1, and EGFRVIII.
