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.
Immobilized 46.8 μg SARS-CoV-2 (Delta) Spike Trimer/1mg Beads can bind human ACE2 (Cat. No. AC2-H5257) with an EC50 of 1.260 μg/mL (QC tested).
Accelerated stability test. After placing the lyophilized beads at 37°C for 7 days, binding activity between the SARS-CoV-2 (Delta) Spike Trimer-coupled Magnetic Beads (Cat.No. MBS-K038) and Human ACE2 proteins showed little deviation from the unaccelerated sample (%RSD<15%). Data were measured on day 0, 3, 7 respectively.
Freeze-thaw stability test. After different freeze-thaw cycles, binding activity between the SARS-CoV-2 (Delta) Spike Trimer-coupled Magnetic Beads (Cat.No. MBS-K038) and Human ACE2 proteins showed little deviation from the unfreeze-thaw sample (%RSD<10%). Three freeze-thaw cycles were performed.
